Help! Live mixer/Interface hardware

[DRTYWRKS]

I'm about to pull my hair out looking at all the mixer/interface combo's out there. Anyone know if its possible to get
a decently priced 2 or 4 channel mixer with usb interface and midi mapping for the knobs, faders, and cross fader.

Bonus points if it has built in USB hub.

I found a couple things out there, but nothing that really hit the spot without breaking the bank. I'd be willing to spend around $500.

Denon DN-X1600
was the best I could do.

M-Audio X-Session Pro would probably work. $100 or less if you can find one. Its REALLY cheap though, might be even too cheap for what you are looking for. You can beat on them pretty good though.

I would say MPD32 maybe.
EDIT: you can tweak every knob & fader almost at wish.
