I need some advice on picking the right audio interface. im building a small recording studio in my house. so far i have a macbook 2.0 w/1gb RAM, Reason 3.0, and an m-audio axiom 49 midi controller. I want to import vocals and guitar. so I was thinking of getting the mbox 2 becouse it will be useful when i start classes for pro tools audio engineering. and plus its used all through out the audio industry. But I heard it was a bit over priced for what u get ($495). I was also looking at this http://www.sweetwater.com/store/detail/MobileKitEDU/ seems like a good deal, but is the interface any good?good preamps? i also wanted advice on a good recording Mic. under $200 i was thinking of the Rode NT1-A, someone recommended it to me. Do all audio interfaces come with preamps?
