I have one, and I agre the rumble was horrible. The motor is tiny, about the diamater of a silver dollar. The spindle and bearing are also light weight. That said, I used alot of lead shot , a Sorbathain record mat, and a ton of sorbo wraped in strategic place, and the sound shaped up fairly good. If you get one for $50, it is ok, I wouldnt put a lot into it. One other thing, if you can get the Rabco arm adjusted to where it is not weaving back and forth (over and under adjusting contsantly) it can sound good, btter than most mid fi tables once you get rid of the rumble. You are better off spendng money on a good Rega P2 used than the HK, sorry but that is the truth!
