Sitecom USB wireless sticks work perfectly with OSX and using the latest Ralink drivers. I am using the WL608, which uses the RT2870 chipset, and I did had to have to add it to the Info.plist, but this thing is so new it is not even on the Sitecom website yet. You can get it at Mediamarkt and it is very small and costs something like 19 euro.
