Sorry not to respond sooner; I didn't see this until now.
What I've heard is that there are several musical instrument factories in the
Reghin, Romania area, and that Mehi is one. Some webstuff reflects that the "Calin Wultur" shop is there. Most of the Romanian instruments which make it to the USA bear labels from the importer, not the manufacturer. Consequently, although it is highly likely that there are a bunch of Mehi basses in the US I've never heard of a bass that actually carried their label here.
Punch line is that some Romanian basses are built heavy and some are not. The best sound very nice. Play it and bring somebody to hear it. You could find a turd or you might find a deal.
