Getting the Hardware
If you go into your local electronics retailer, it's unlikely you'll find mini-PCI wireless cards on the shelf next to the other wireless client adapters. But a Froogle search for mini-PCI 802.11 brings up plenty of options, although at prices much higher than you'd expect (or want) to pay.
An alternative to paying top price for a mini-PCI card is to "harvest" one from a product that uses one internally. I compiled Table 1 by digging through my past product reviews and you can use it as a starting point in your hunt for less-expensive wireless mini-PCI cards.

An 802.11g wireless router is a good choice for harvesting, since it will still function as a non-wireless router when you remove the card, or even just an extra switch if you don't need a router (just disable its DHCP server). But you may have to search on eBay to get older versions, since current versions of popular bargain-priced routers such as D-Link's DI624, NETGEAR's WGR614, and Linksys' WGT54G all have integrated radios (part of the reason why they're so inexpensive).
TIP: Vendors usually add a version number (example: WGT54Gv2 or similar) to the product's model number when they make a significant design change. However, retailers generally only stock by base model number (example: WGT54G), so if you're buying on-line, you won't know what you're getting until you receive it. Fortunately, manufacturers usually do show the version number somewhere on the product box. So if you make your purchase at a brick-and-mortar retail store, you can verify that what you're buying is the model you need.
