Replying to What camera should I get?

Yeah, I looked around for this thread. Found one on video cameras, if there is a different one, please point me towards it.

So I don't have much of a set budget right now, I would like to buy everything cheap, and will buy stuff that is practical online or craigslist used

Anyways...
I know absolutely nothing about cameras.. But I really want to get into action sports photography(mtb, skiing, skating, etc.) And then a camera that could do some film(but better photography obviously) would be nice.

Thanks
