There's an Audio Store down in Vancouver that had one of these on display. When the owner was giving me the guided tour, he pointed out this tremendous little gadget.
He even did a demonstration where he scratched an LP with his keys (I could barely watch - nails on a chalkboard type deal) and when that LP was played back, you could barely tell there was several enormous gouges in the record.
I did ask about CD-4 compatibility and some more involved questions about the unit, but he simply wasn't as "up" on the unit as you'd expect. It is a good unit, I can testify to that, but for the price.... eeeeh.... you can find a better copy of the record you'd want plus a disc washer - hell, even one of those ultrasonic record bath's for a quarter of what this would cost.
