Is it worth the effort?
Or, should I just buy a 002 or 003?
Well how badly do you want those extra 2 inputs? It's really not much effort...buy a spdif interface, plug it in...good to go!
well...do you need 18inputs/outputs? or do you just need 4i/o?
There's going to be a BIG difference in price..what do you plan on doing with your rig?
The main thing is being able to properly record drums.
And, I would like to have a better mic-pre than the one on the Mbox 2.
