Just noticed this thread... timely as I wait for my JB3 replacement to arrive
Been using one since I got into taping in 2007 (well, I taped a few shows with a borrowed rig in 2006... that was with a JB3 as well). It was working well, but transfers got to be too much of a bear. My primary computer these days is Win7, so I can't do a direct transfer. I was transferring to my XP netbook, where I'd process if I was on the road, or transfer (generally via thumb drive) to my PC to do post. Of course, that initial transfer just CRAWLS at USB 1.1 speeds (they dropped 2.0 when they added Firewire... makes sense, right?). I also lost part of a recording last year when I filled the hard drive, and lost part of my first real tape with the friend's JB3 when heat caused it to shut down (full disclosure: it was Tampa, in August, outdoors, and I made the mistake of wedging the JB3 into a bag).
All that said, it served me pretty well. Gonna hang onto it, I think, because there's no real way to get rid of it
