Replying to Camera to film a snowboard/ski video.. what should i buy?

hey I got a job, saved some cash, and i really want a decent camera to film some tricks this winter. a couple of friends and i want to put together a semi-long,well made movie, and i gotta figure out what camera to buy. my price range is like between 500-800. i dont know if i should go with all digital stuff and not use tapes, or if i should go with mini-dv?
just give me some input.. thanks!
