I'll need it to record on my 1.2GHz iBook, so far I've used Logic Express but would like to try different hosts. I'll never use more than one input at a time, either guitar, mic, or MIDI, so a high number of simultaneous inputs and outputs isn't relevant. I guess it also means that I can make do with USB 1.0. What I'm looking for in particular is a good headphone output, since I have to do mixes with phones. Can't spend much more than $400, maybe $500 if it's a great deal. Okay, so I've considered the following: Edirol FA-66 (don't know anything about this, except the features seem to fit the bill) $400 M-Audio FW 410 (looks nice, but haven't they had lots of driver problems?) $300 Presonus Firebox (generally good reviews) $400 Lexicon Omega (ugly, but lots of features for the price) $300 Mackie Spike (ugly, but on sale where I live, and I'd really like Tracktion) $300 Steinberg System 4 (I'd like Cubase SL just to get my hands on Cubase, don't know anything about the hardware) $400 Any input from user of these would be much appreciated. Specifically about the quality of preamps, converters and headphone output. Thanks!
