I have the mbox and love it. If your song is good, a cassette recorder is adequate, right? I tracked a whole band on Sunday (well, mine, but it is a whole band!) using the mbox and my laptop (not powerbook,a pc, but same thing really). We did drums with a kick mic (sennheiser) and an overhead (tape op ribbon) both into an m-audio dmp3 into the mbox, tracked everything else similarly (mojave modded adk mic, superlux sdc's, and a senn e608 were the other mics used at various times), and I think it sounds great. We are doing preproduction for an upcoming cd to be recorded in a very nice studio, but I like the spirit of this recording and it was fun to work with these limitations. I also work at a studio with the 002, and take things back home all the time to work. Do the best with what you can afford and it will all be good. Plus. mbox can be had for $299 now at various places.
