I found these for sale on Newegg's website & bought one to try to get my wifi working.......

They work great!!!!!!! Fully Mac compatible (I'm using iDeneb 10.5.5 & using it currently!) and it's twice as fast as my Intel 5300 built in Wireless N in Windows XP as well!!!!! I'm currently getting 280Mbps with this thing!!!! (plus, they're on sale right now!)
