Generally PC WiFi adapters, be they USB, PCMCIA or PCI, are very "dumb", and offload a MAJOR portion of work on the PC's driver. There are exceptions of course, and aiming for adapters that are used on less powerful devices (i.e. CF or SD WiFi cards meant for PDAs) can drastically reduce the software support. Another option, although too big for the op, is WiFi routers. They are so cheap today I often see them on sale for $10. Some of them have wireless client capability, meaning they basically act as an Ethernet to wireless bridge, connecting to a normal access point. I've got one at home that works very well.
