Reply to Good external sound card?

Does anyone have any recommendations for a modestly priced and decent quality external sound card? I am looking at the M-Audio M-Audio Fast Track USB Audio interface - 48 kHz - 24-bit right now but don't really know much about it.

I am trying to use it to split audio from my computer into channels so I can use my Xone 42 (which is not midi capable) to EQ while mixing. That is possible right? thanks in advance for any help, I am in the midst of upgrading all my shit gear so I have many questions
