I've got an old JVC GR-DVX 8. I got it 2-3 years back so it's quite old now.
I've found it to be okay and did what I needed it to do. I made sure I got the version which had DV-IN enabled as I wanted to mess around with it via IEEE1394. The build quality of mine was okay, nothing amazing however. One of the small screws on the bottom fell off after a while but I just put it back in and put a dab of thread locker on it.
THe only problem I've found is that the batteries are kind of flakey and don't last very long.

Not sure how useful this is to you considering it's such an old MiniDV camera.
