I need an all-in-one recording interface for my laptop. Very unhappy with the M-Audio MobilePre USB. Like to spend 3 to 6 hundred depending on quality and features, but open to a bit more. More inputs would be nice, but 2 very high quality inputs at a low price would be desirable. Considering: Edirol UA-25 Lexicon Omega STudio Mackie Spike Focusrite Saffire Presonus Firebox or a Tascam FW-1802 Any suggestions on the above or not listed. Primarily looking for price,soundquality,features.
