Don't get me wrong--I was just giving some more info on the JB3. Personally, I'm split regarding the JB3. Probably why I run one alongside a DAT. Very nice box, great for transfers, I'd definitely recommend one over MD. Compared to DAT, I'm not quite there. Pretty crappy compared to DAT if you're running analog in. Digi in, the JB3 is much better, though I still find it's meters to suck. So unless you have a pre/AD that has good meters, the JB3 will be somewhat difficult to work with.
My preference would be to still go with DAT if you're looking for a unit to record on for awhile (and folks will still be recording on DAT for quite some time to come). But a new JB3 will be less money than a well-functioning used Sony D7/D8 with 7-pin cable. If you're thinking about the HD recorders that are just around the corner, a JB3 might be a good unit in the interim until you can pick one of those Sound Devices babies up.
