in my 30+ years owning the VPI 16.5 it has been dead nuts reliable, works well by direct comparison to a good US machine, is still in production, and is well supported by VPI. Unless one is burning to have a US RCM or wants the added convenience of the $5000 Clearaudio vacuum machine, I don’t get why you’d look for a used foreign made RCM with questionable if any factory support.
US=UltraSonic. Sorry.
