There has been one on epay for a while now that has a $25 opening bid. It's been listed at least twice now with no takers. I think it's still there.Here it is.

Looks like it didn't sell again.
These old Garrards have a decent platter assembly, but very massive tonearms for modern cartridges. Might make a nice table for a newer tonearm conversion.
