I researched this for my parents who inherited my Mac Mini. I found that the RocketFish webcam comes with Mac drivers, indeed will work with a Mac Mini, is of reasonable quality (they use it quite often to video iChat with me using iChatUSB) and is only $50.
Heck, I got one for myself to use with my Windows PCs as well.

Since iSight external cameras are ridiculously expensive on eBay, can anyone recommend a good webcam to use in it's place?

using iChatUSB
There is native OSX support for USB web cams since 10.4.9 so you do not need to use iChatUSB anymore.
