The WG111T is the only netgear adapter I've ever tried, and I wasn't impressed. I'm sure in many cases it does the job, but do not buy it if you have an AMD CPU. It doesn't like them, at least with the revision I had. Kept causing hard system lockups requiring forced shut downs.
Is there any particular reason you want a Netgear branded one? They all work the same since wifi is a standard. I personally use a Linksys WUSB600N v1
