Reply to Cheap but respectable audio interface? (*into* computer)

Looking to record my DJ sets into Audacity.

Work flow: CDJ 900 -> analog Rane mixer -> PC.

It seems that all the reviews I'm reading on audio interfaces are for outputting from the computer, so many of the budget gadgets don't even have inputs.

That said, I trust RCA to 3.5mm Microphone In on my motherboard isn't SoundCloud worthy, but I really don't know.

I'm the type who prefers to buy WAV's over MP3's, so with this in mind, I don't want to bottleneck the quality along the way. Can anyone recommend a respectable option for this? For example, is something like this in-line with WAV quality? http://www.behringer.com/EN/Products/UCA222.aspx
