I have a TiBook/500 and an iMac/400. My neighbor has a wireless network setup in his house to his cable modem service. I'd like to get a wireless card or a usb adapter to use in either the TiBook or the iMac and connect to his service, but don't know what to choose that will work. We tried his peecee laptop in my house, and the connection is great! Airport cards are expensive (and won't work in my iMac) but there are a lot of alternatives, just don't know what will work with OSX 10.2 or with Macs at all.

Any suggestions you might have would be very helpful. I've seen the Farallon card and USB adapter (trying to find one on eBay but know there must be other alternatives. Thanks for your help!
