Which turntables?

The Sony PS-8750 is a real winner as long as the motor is speed stable (Dekay's test is the one I would do). The other two are good tables as well. FWIW, I find that the big brothers of the PX-3 don't deal terribly well with low compliance carts (so, jumping to conclusions as I am sometimes wont to do, I expect the PX-3 wouldn't either).

Personally, I am not sure it matters whether Yamaha manufactured it or not. If Yamaha designed it and had the good sense to have Micro Seiki manufacture it, more power to them. When I am back where it is, I can check to see if it says anything on the back about MS manufacture. In any case, the PX-1 sounds great.
