Inexpensive 802.1x AP that does 802.11g or 802.11a?

Can anyone recommend an inexpensive AP that does 802.1x (EAP) that's
802.11g or 802.11a? It's time to upgrade at home. Ultimately, I'd love
something dual mode.

Please don't say Cisco 12x0--too spendy. I want to do EAP on a small
business network in the middle of downtown with plenty of people scanning
for open APs, and WEP isn't going to cut it, but we want to go cheap, we'll
probably use inexpensive G cards from Dlink or Linksys. I know they each
have "g" products, but don't know about EAP/802.1x support.

Gratz!
