atheros5000 cards woun't work currently with Sam series.
But if /when Neil gets it work it would be good choise.
Atheros5000 and Prism2 are chipset used for wlan cards, several manufacturers are used them. For here Finland easiest to find is atheros5000 based card D-Link DWL-G520, netgear cards are also quite common.
Problem of prism2 based cards is that they are hard to find, it is anicent chipset, speed is max 11mb, when atheros is 54mb
I would be very usefull if more people could report their experienses of atheros cards to this thread
