I bought a new Star III about 1989. The only thing I've done to it is add a different platter mat. Haven't done any of the maintenance suggested above. The motor is as described above--I have it about 8 ft. away from my listening position and its noise is inaudible from there while a record is playing.
I basically agree that it's pretty much a set-it-and-forget unit. I live in earthquake country, so I check that it's still level after a big earthquake.
It's so nice having a turntable that flattens warped records.
