For the kind of money high end turntables command the speed should be dead on, no matter what the incoming voltage, within reason. Or it should be adjustable.
Speed is just as important as stability of speed.
I like to play guitar to a lot of music and if the speed is not accurate the guitar is out of tune with the music and that is frustrating.
I've got a Transrotor Fat Bob S. I was fortunate because it came with the a speed controller that included fine adjustment for 33 1/3 and 45.
I'm not sure I agree that any cheap controller will do the job though.
If it's not rock solid that will drive you just as crazy.
