Jb3 all the way...
Its not as cheap as you think--- $200-250 new or usedfor the jb3
plus $30-50 for that all too necessary xtra battery.
and some kinda way to get optical to it.
~$50 for a c02...which I have had no problems out of so far...taped 10 shows or so with it.
sooo for about a $450 investment, you can get a jb3 rig that can be plugged into anything that has spdif outs and record.
not dirt cheap, but not really a bad deal for what you get.
30+ hours or pure wav files, with good file system and lightning fast transfers via firewire!!!
