I just purchased the Belkin F5D7050 from Caretek for $45 with the hopes of getting 802.11G connectivity for my iMac G4 running Tiger (10.4.7) through USB. The 10.3 drivers on Belkin's website didn't work at all (as of 8/27/06) but I did download the ralinktech driver and it worked right away.
See link: http://www.ralinktech.com/supp-1.htm
I downloaded this one: RT2571W/RT2671 Date Version OS Version Release Note USB 2006/07/07 Drv1.1.4.0 10.3.X ~ 10.4.X Doc
I hope that this was helpful to anyone who want an alternative to finding an old Apple Airport Card.

"Success! I have a Belkin F5D7050 v3000 uk usb wireless g adapter. I've got it working thanks to William Warner and Jay Bratcher on a G4 Mac Mini running Mac OS X 10.5.7. First I installed the D-Link WUA-1340 drivers from http://www.dlink.com/products/support.asp?pid=477&sec=0#drivers, install the 10.4 drivers and restart. Second I installed the Ralink USB (RT257x/RT2671) drivers from http://www.ralinktech.com/ralink/Home/Support/Macintosh.html, install the 10.5 drivers and restart. The nice thing about the D-Link drivers is a handy menu bar item showing network connections and signal strength."
