There is one of the Pioneer PLC-590 tables on eBay right now with 2 hours left on it. It has a decent vintage SME tonearm on it. It is a very high grade table, though the arm is not up to modern performance levels. But on the bright side, that arm has a high resale value. You should easily get $300 at least just for the arm, and you can replace it with a superior Jelca SA250ST arm. The table itself, you would have to spend near $2000 to get a comparable performance table NEW. I expect it will go for $600 roughly on the auction, but be quick, only 2 hours left.
Forget the PL 90. That is an even higher performance table, and comes with a modern level performance arm as well. But it will go for $1000-$2000 easy, depending on condition. Plus it's exceedingly rare.
If you want a top notch performance table out of the box, used, look for Denon DP-59M. This table is both superbly designed and has superb performance. The tone arm is probably one of the highest performance arms possible. But the arm is also the weak point. It's an arm with accelerometers and position sensors and feedback transducer and servos embedded, connected to a computer system that actively cancels resonances in real time and makes other corrections. The problem is, there are no parts available to fix it or the computer, if anything goes wrong, making it a concern from that standpoint. But you can get an excellent condition one for $500-$700, depending on condition.
