If I may, I'd like to change the subject:
I believe an idler drive is superior to a belt drive.
I have a few belt drives in house: Heybrook TT2, Linn LP12, Michell Gyrodec. All with every upgrade available.
My 'new' Jean Nantais Lenco 75 idler drive blows them out of the water. The speed stability, therefore PRAT, of the idler drive is addictive.
Regarding newer tables. While it is possible to build a good motor today, the metals used in the motors of old are difficult, and expensive to get. An equivalent motor today would approach $700.
If you are a 'tweaker', get the Thorens. If you can hold off, wait for an idler drive, and then tweak. Remember, being an audiophile is a journey, not a destination.
Instead of telling you a long story, let me get to the point. And yes I'm going to shout: The tonearm BEARING is the most important part of the analogue playback system. Beg, borrow, steal whatever money you can, and buy the best tonearm you can afford.
Here's an analogy: consider the size of the diamond on the end of it's cantilever. Think of the miniscule movements in the record groove. Now think of the length of the tonearm tube. If we 'grow' the diamond to 1 inch is size, the relationship to the bearing will put the bearing hundreds of yards away. Any movement in the bearing will smear the movement of the diamond.
Sorry for shouting.
