This model can be had virtually any day of the week from eBay for <$2 shipped. If you're a real tightwad and play out an auction, probably <$1 shipped. In fact, I bought one just a few days ago for $1.28. Will be using it for my hacked WL-520GU router (http://www.tinkernut.com/archives/2387).

Got one on my desk, the headphone plug came off inside the circuit board after a few weeks of plugging unplugging

All these cheap USB sound cards are pretty flimsy. Even the case feels like it's going to come apart with little effort. If you're going to be plugging/unplugging often, I suggest taking it apart and judiciously using some crazy glue to keep things together.

i bought two, it worked as decribed.
