I'm replacing my firepod and really only require one input at a time so the two front instrument/mic inputs on either the box or the studio mobile should be more than fine.

I'm not really sure the difference between the two even after doing a little research. A buddy of mine works at a music store and can get me the studio mobile for $240 which is why I'm considering it over the box but wanted you good people's opinions here on it. Thanks everybody.
