...I've got it... I picked it up from a friend, used, for $250... a sweet deal, considering street prices are still $400-500... it's got alot of capabilities!
the cardbus interface is solid, w/ it's own processor for sound... 192KHz is insanely fast, I don't ever use all of it's capabilities, though I might. Overall, it's a great 'mini studio' interface... but, I don't like lugging around a power adapter and cords for it... so, I bought an Echo Indigo DJ, for DJing... I've considered buying something USB powered, or the Echo I O cardbus, for mobile recording...
generally, I consider cardbus to be the most solid and powerful PC sound interface.

I've got to say I'm pretty happy with mine...I haven't really learned it the way I've learned Ableton, but it works pretty well. I need to trouble shoot it a little, sometimes it gets buzzy, but I think I have my sample rate wrong, so its probably me. I think if you really learned it, it would be a very cool device to have around (I just use it to record and then move on...)
