Gopro. Get the little monitor and a couple batteries. You can change the lens angle in camera, so it doesn't always have to be a fisheye.

Probably the best you're gonna get for 400, and you can hit it with snowballs all you want.

I already have one. Im looking into camcorders for edits, as well as school. Thanks for the reply though.

I'd look around for a used or refurbed Canon HF M41, you should be able to find one under $400. If you can spend a little more, go for the HF G10. Keep an eye on the refurb section on Canon's site, they have big sales every month or two and if you're quick with it you can score a great deal, and it'll have a warranty from Canon.
