If your loving protools then definitely get the 002. If your so so about it then go the other way with another firepod. Either way is gonna be good i think...
Hmm, that's a tough one - if you wanna stick with PT, then I'd say go for it, as long as it's an even trade, cuz you can get the 002 modded by Black Lion Audio to make it actually pretty good.
Have you gotten your MBOX2 to work reliably in Cubase? Mine (I'm on a PC, granted) has absolutely horrendous recording latency (though it's fine in PT, I guess they build-in compensation)
Yeah the mbox 2 works great in cubase for me. It has more latency than the firepod (7ms at 256 vs 5ms with the FP), but all USB devices I have owned have been that way.
