[DuoList] OT / cheap wi-fi fix for Al-book

[mko]

Hi all. Not a Duo Q per se, but..
Looks like my Airport card burned out
in my Al-book (G4 15"). I was enjoying free
Wi-Fi at a local restaurant for about a week,
suddenly couldn't get a signal last Friday.
Their wi-fi cash sys is still up so I know it's me.
I Googled the prob and found a tip about an
Asanté FriendlyNET card, AL5403-XG, but
they're discon'd, and no joy on ebay either.
Local shop said $125 for new Airport card,
+ $45 install. On the downbeat at the mo so
am looking for a cheaper fix.
Help?

TIA
