Got one here I use for gigs (not that I have time for gigs any more

). I like it.
Sound is not too bad - for the price it's
excellent... remember I am a snob
Headphone out is very passable/decent. Connectivity is just what you need with pretty much all bases covered, with good quality. And I can confirm from first hand experience that it survives airports, aeroplanes, muddy fields in Lithuania, drunk Irish people, and the occasional accidental hard drumstick smack. The knob/buttons are more solid than you think. It has literally never let me down at a gig, and that's priceless.
For the money, I don't think there's too much competition really. AND (!!) it is bus powered.
FWIW I have just set it up to run from my net laptop directly into my mastering convertors so all I need to do is press a button and I can audition stuff from here/myspace/AIM etc though the mastering setup. So if I have time, I'll be able to checka bit more stuff out and hopefully help out a bit more round here.
Anyway, it's good.
Edit: running XP here, not Pissta.
