It's getting kinda out of hand how you're using the forums as google. You could look up [url=www.buzzillions.com/reviews/sabrent-usb-a11n-wireless-n-adapter-anten-reviews]reviews[/url], google "best wireless adapters" or "good wireless adapters", cross reference other places, etc. You are completely capable of researching something like this if you just google and read other forum posts (there's hundreds of posts on places like tomshardware and what not).

If you want it only from Fry's, here's what you can do: sort by price, filter by what specs you want (aside from PCI vs USB vs a laptop card, if you don't know them, you probably don't have to care about them). Search for the adapter model on google. Check out reviews on Newegg, Amazon, and other retailers. Draw a conclusion from all the data out there, but realize that most adapters are basically the same unless you're trying to go through 5 walls or something. Biggest thing I'd worry about is how long they last (check reviews for this), because nano adapters have been shit to me and break in days.
