What's the best buy for 2nd hand at 200 USD?

Late 70's Sony direct drives are still decent values and under rated performers. Look for PS-X6, PS-X7, PS-X60, or PS-X70 or variants there of on the auction site.

Unfortunately, your NR1403 does not have phono inputs. That means you'll need a phono stage (or a different receiver) in addition to a turntable/tonearm/cartridge. Some entry level tables have a phono stage built in, which should help with the budget. I've no experience with those so can't recommend anything.

I owned Dual 1217 and 1229 turntables in my college days (back in the 17th C.) and concur with that recommendation, but they don't have phono stages. Unless you get lucky, a Dual may be a budget-buster unless you can find another $100 or two for a phono stage.

As several have said, the old Sony PS-X series punch WAY above their weight, the PS X-7 has a carbon fiber arm and will smoke any Dual ever made, most Thorens as well etc.

MofiMadness,
The AT turntable is nothing like a technics SL1200 except for outside looks. I strongly second the recommendation for the Sony PS-X___ series of turntables.

The predecessor to the Sony PS-X7 was the PS-4300. It is listed on AudioAsylum for $175. Read the review on The Vintage Knob.
