As a long time owner of a remanufactured early version 401, which I understand is not a million miles away from the 301, the main thing I would say to look out for is rumble, especially if you are using a sub. They have a powerful mains induction motor coupled to the platter with a rubber coated wheel, and the amount of breakthrough seems to depend on idler wheel spring tension, state of balance of the motor, trueness of the eddy current brake disc and the prevailing mains voltage. Modern plinth designs and special stabilised lower voltage power supplies are supposed to fix this, so perhaps I am being too pessimistic. But even specialist rebuilt ones in proper plinths can still rumble, as I found out out lately.
