I am looking to get an audio interface and was originally looking to get the Firestudio Mobile, for 300 but it only has 2 pre amps which is enough but more would be better. And then I found the M-Audio Fast Track Ultra, (http://www.sweetwater.com/store/detail/FastTrkUltra/) which is (On B&H) actually 30 dollars less then the Firestudio. But I keep hearing how bad USB is, I don't mind a complicated set up. What makes the Firestudio so good? I understand it probably has better pre amps then the Fast Track ultra, and I understand that is important, but it's even more importent to me that I have 3 inputs (And the Fast Track gives me 4) technically I could get along with two. But it would be nice to have three. So should I get the Firestudio or the Fast Track? What are the pros and cons?
