How often do you upgrade your turntable?


And how do you know that it is time to do it? I mean table itself, not arm or cartridge, though this might of course follow.

I have been upgrading every few years but since I got my VPI Aries 3x3 I will be set for life.
I used an entry-level turntable for almost 30 years before I replaced it with a (better) entry-level turntable. And then I upgraded turntables twice in 5 years. For the first 30 years I was a real vinyl cheapskate and wouldn't spend the money on a new turntable. I upgraded the speakers several times and upgraded the amplifier, but never the turntable.

I came to realize that the turntable (and the cartridges I used) had been limiting the quality of sound I was getting from my stereo; that is, the vinyl setup wasn't in the same category as the rest of the system. So after replacing the first turntable, and enjoying the sound from the improved entry-level turntable, I decided to find out what was possible from vinyl. I bought a turntable and a decent cartridge that was a few steps up from the entry-level setup. Wow, what a difference. And then I bought a decent phono preamplifier. Now we're talkin' great sound! I couldn't believe how much better the whole system sounded. I finally got it;

I listened to that setup for a few years and then I made some extra cash one summer (working lots of overtime) and
... bought a good vinyl setup that I'll probably keep for as long as my first entry-level turntable.

I too don't plan to upgrade my Nottingham Spacedeck any time soon, and unless I am ready to go over $10k or so I would only upgrade to another Nottingham.
Theoretically speaking, if I had , say, $3000 for upgrades right now, what would I do? Would I upgrade the table, the arm plus cartridge, cartridge plus phono or integrated amp?
That would be tough. Probably either cartridge plus phono or the amp, also depending on opportunity.
Back in May I put a new arm and sub chassis on my LP-12. I just bought an SME20/2 with an SME IV.Vi arm. I think I'm done, unless another good deal comes along...
