M-Audio Firewire 410 here... It's cool.. but if you don't need a breakout box for a laptop or somethin.. Go with a pci card.. You can multiply cards and add extra i/o later with SOME? m-audio pci's.... Added bonus is that you can get ProTools m-powered, if you so desire.... I use it...
Firewire 410s are like 200 dollars now, i think...
Lot less than I paid...
