Final Fantasy Hacktics

I need a camera for making videos.  It can't cost more than $150, and I have to be able to find it at Wal Mart.  Also, andy Windows or Mac only shit is a no go, since I'm an Ubuntu-fag.  Ruggedness is a plus.

And how could I keep a camera charged while alone in the wilderness for weeks or months?  Is there such a thing as a hand crank generator, or could I use one of those hand crank radios with a usb outlet to charge it?

Concerning charging: I'm pretty sure your average convenience store will allow you to use an electrical outlet for a half hour or so.

I mean literally out in the woods.
