Yeah that should also work, I was only looking at Newegg because it's easier to filter categories compared to Amazon.

The Behringer one uses a relatively cheap codec PCM2902 from TI ( http://www.ti.com/lit/ds/symlink/pcm2900.pdf ) but seems to have slightly better specs than the C-media IC ... though it's understandable, this one only has one stereo input and a stereo output on a chip, while that other one is 7.1 out and a bunch of other things (can be linked to a microcontroller and other things), so it packs more things in the chip, which can lower the audio quality slightly.
It will do the job. Here's a review of the product if you didn't already find it : http://nwavguy.blogspot.com/2011/02/...02-review.html

Behringer is a good brand - I generally don't like it because they have the tendency to use good chips but bottom of the barrel capacitors (often chinese unknown brands) which can cause reliability issues in products of their that have built in power supplies or dc-dc converters.

In this particular type or product, the audio chip is powered directly from 5v from USB, so there's no power supplies or high frequency stuff or things where could capacitor quality could really affect things much, so even if they use cheap capacitors the audio quality is unlikely to be affected, at least for the first year or so of usage.

@Ghitulescu : some of their recent stuff is actually quite nice. The drivers were a big problem of Creative products... in the case of their usb products which doesn't require drivers, you have the significant issue gone.
