I got day before thanksgiving microsoft PCI card
54G for $59
(comes with rebate of $10) from officemax
they have laptop and desktop cards and access points (runs windows CE) on sale.
They work great with kernel 2.4.22. With sale you get access point for $199 -
$30 from office max (for spending over 150) and $40 in rebates so you pay $129
and get cards that work great with this project
