PS: Read the FAQ, the RFAQ, Repeat.

Edit: If you wonder why I mention to read the FAQ and check the FCC number is because the Kismac Forum is full of people that purchased a 1) non supported USB 2) purchased a knock off or a USB where the manufacturer had silently changed the chipset. the FCC number is one of the best guarantee that the chipset is correct. Do some due diligence before buying and you'll save a lot of time, money and/or trouble. I would advise you to buy from a brick and mortar shop if you can. At least you can return the USB at no fees if not working.
