Video standards (was Re: digital cameras)

Does anyone know if the U-Max or the V2000 were marketed in the US? I've
never seen (or even heard of) anything like it. Does anyone know how much
one might cost if I could find one?

I like working with the older video equipment (mainly because I can fix the
stuff) My only VCR is an 80's top-loading GE, complete with _wired_ remote
:). The only reason that I bought the JVC VHS-C camera was because the
heads went bad in my old camera (the kind with the separate camera that
plugged into the 'VCR' that hung from a shoulder strap).
