What's a good $35 WiFi Expansion Card?

[newnoob1]

Hi
I'm building a new PC and I was wondering if you guys know any good WiFi Expansion Cards around $35. I'm looking for something similiar to the GC-WB300D. I just don't really need the bluetooth, I just want the 300Mbps (or more).

What is the pc going to be used for?
