Samsung makes a water resistant sports type cam that even has a remote lens adapter. It only records to Memory stick but you can still record up to one hour at high quality and then burn to a DVD at home if you wish.
I think the price is $600 or less.

My wife and I are thinking about getting one for our four wheeling (ATV) adventures.
