Awaking an old thread, I just found and purchased a red HM-V on Facebook Marketplace for $100 with a hard case.
It had scratchy pots, loose knobs, an intermittent output jack, improperly assembled (loose) machines, and buzzy strings.
I cleaned it up, dropped another $100 into it including La Bella "deep-talkin' bass" flat-wound strings in gold, a gold output jack, a can of Peavy Funk Out, and a kit of assorted gold plated screws.
Looks and plays well now, though it is my first, so I can't really compare it to anything else. The bridge is massive, definitely no need to upgrade that, but I will be sourcing plated hardware. The intonation screws and springs are a bit corroded.
I find it super heavy, compared to a Stratocaster (my only other frame of reference). It feels twice as heavy. I got a padded strap to spread out the weight. Others claim it is a lightweight bass.
Not going to part with it ever, because just like guns, I've regretted it every time I've sold one (except a useless .22 Beretta).
