Looking for not too expensive Turntable

I want a vintage turntable for a second system with a tube amplifier. I read the Pioneer PL-12 is good sounding without any jitter due to being belt drive. I can actually hear jitter. I owned a direct drive TT and it had jitter. My Garrard 401 did not have any jitter either. Suggestions? Pioneer PL-12 good?

When it comes to vintage turntables, nothing can beat the price/quality of Technics SP-10MKII (i use teak wood custom plinth), a little bit cheaper and quite rare is Technics SP-20 (i have a spare one). Adding tonearm like Victor UA-7045 will not make this combo much more expensive. Plinth or no plinth is a matter of taste. I would suggest Technics is the best DD choice when it's reasonably priced on used market (best buy, imo).
A PL-12D in good condition can be found for under $200. As a budget TT probably as good as any of the new ones under $400. What is your budget?
I am eyeballing the Pioneer PLX-1000 (new) as there are some really nice reviews out there. I've seen it as low as $613, but I don't know what your budget is? Upturn Audio has an Orbit Special or Custom for less than the Pioneer that also has my attention.
SP10 is not inexpensive.

Just ot make it clear:
the first SP10 does not have Quartz-locked speed control like all the later made and improved models, such as SP10mkII and SP20 
What's your budget.  Big price difference between a Pioneer PL12 and a Technics SP10 Mk2
Budget is $250 for this secondary system. My main system has a $1500 Garrard 401 in custom plinth with 12" tone arm.
How about a RekoKut idler-wheel drive? I have one in my collection and it does sound excellent with a good tonearm!
To me a new Music Hall MMF 2.2 or a Pro-ject Debut III from Music Direct, Audio Advisor etc. makes more sense. You’d have to step up $50 (both are $299), but you’d have a brand new table with the benefit of 40 years TT building experience. You obviously like vintage, and I get that sentiment (both styling/nostalgia or in the case of tubes, audio superiority). I sold mainstream audio in the 70- 80s in retail, and then some more esoteric stuff out of my house in the 90s. Ive sold and owned,(who hasn’t!), the PL12 or one of its variants. I doubt it offers the same degree of isolation between the cartridge and motor/ environment that the two newer tables would, (or track as well). In addition, that $50 gets you a new cartridge, belt, flawless dustcover, etc. You might get a new belt for the vintage Pioneer only to find out the four decades old motor is having issues. The new ones of course do have a warranty and typically a trial period, (tables may be tricky, so I’d check if you are concerned). Better yet,  I’d run these prices by any local brick and mortar stores that carry these tables, I know my local Pro-ject dealer is very competitive with online sources.

Don’t now about jitter. May be you are hearing pitch variations due to the flexibility of the belt - wow and flutter. DD is better technology. Pioneer DD is actually very good in the late 70’s.
Denon DP80 can "beat" SP10 Mk2 by a small margin.  Can be found for $600 to $900.  (I owned them both, both in custom slate plinths, ran them side by side in my system. End of editorial.)

What you may have heard from your un-named DD turntable may have been motor cogging, but it was definitely not "jitter".  Jitter has a very specific definition related to digital audio technology.  No need to muddy the water by misusing terms.  Since you don't name the offending DD turntable, it is difficult to comment, but your experience with one particular sample does not prove that you would not enjoy some other refurbished vintage Japanese DD turntable, like either the SP10Mk2 or the Denon DP80 or any of several lesser models; other than the Technics brand, they are all relative bargains in today's market.  By this I mean that the cost is a fraction of what you have to pay for similar performance from a new belt-drive.  And then there's also the Lenco L75, for the biggest possible bang for the buck. Straight out of the box, the Lenco is excellent, but to get the most out of it, the Lenco is for a person who likes to tinker.
I'm very happy with an Audio Technica LP AT5 I bought. Changed the factory cartridge for an Orfoton Blue and substituted the included rubber mat for an acrylic one. Also hooked it up with my higher end interconnects. 

It sounds really good for a $450 - $500 TT
I can recommend any of the vintage Empire TT's. Belt drive and a high torque motor. I own three - with a fourth on the way!
Tons of choices under $250 on ebay.  Just budget enough for a new cartridge or stylus.  A cheap and cheerful Ortofon Red, Grado or Audio Technica should do the trick.

 The OP said the budget is $250 for the whole system 
If one was buying new, the Audio Technica LP-120 comes with a AT-95E cartridge. A friend of mine owns one and it seems very well built for the price (~$250 Amazon). I would also check out Music Direct, The Record Doctor, and Audio Advisor for alternatives.   
Dear Chakster,  I guess I was responding to your bald statement that "nothing" can beat the SP10 Mk2, presumably in its price range and in the category of vintage direct-drive types.  My remark was just meant in fun.  However, I agree that "below $250" is not the price range for either the DP80 or the SP10 mk2.  I've held on to my DP80, even though I do not use it regularly, just because the market value is so ridiculously low compared to its capabilities.  (I listen to the SP10 Mk3 and the Kenwood L07D most of the time.) I'd prefer to have the DP80 around just to look at, rather than to sell it for the too low price it could command.
I don’t know any other top class turntables with such a high torque like the SP-10mk2 (or mk3). In terms of usability this is the best, i wish all my DD could immediately start/stop like the SP-10mk2 or at lest like the Technics SP-20. But none of them (Luxman PD-444 or Victor TT-101) can compete with Technics torque. Never tried Denon, but i’m sure the platter is like Victor’s. I know they have another advantages and i know why the torque is not that high and the platter is not so heavy. But for usability the high torque is amazing feature, that’s why it was studio broadcast turntable, that’s why even lower technics are "disco" turbtables.

The visual part of the hi-end gear is important for me too, i prefer the classics, in terms of design those SP-10mkII, SP-20 are so nice (but not in the stock obsidian plinth, imo). 
  Yes as Mesch said there is a new Audio Technica table for $250.My brother bought one but I don't know if it's the same model # but it was $250. and it sounds surprisingly good with vintage AT155 cartridge and even has VTA adjustment. A very nice looking rig brand new.

All the Denon DD have an electronic brake and they do brake rather quickly. Not a quick as the Technics MK2/3 that use a mechanical brake. The BIG Denon the DN308 originally have a mechanical brake in addition to the electronic one.  On my Rebuilds I do eliminate this as not stops with in a 1/4 revolution with the electronic one alone.

Good Listening
