Cisco recently announced they were killing the Flip line of camera's. Since this what Ken uses for his vids and the quality is always good (minus low light situations) I thought I'd post this link that shows places selling them for cheap.

Cheap Flips
I'd almost say they're more headache than they're worth, but I guess if you can get them cheap, they can be of use. They're crappy in indoor light, or even outdoors when it's overcast. When it's sunny out though, they shoot a pretty good image. They take forever to charge, and I had problems with that too. But yeah, if you can get one for under $80, you can get some use out of it.
