If you are just looking for something simple and easy to use, look into a
Flip Video camera. I use mine more than I use my regular camera. They are between 100 and 150 bucks, hold between 30 and 60 minutes of video, and have a built in USB thingey that plugs right into your computer. Powered by two AA batteries. They are about the size of a cigarette pack.
Not something you would want to film the birth of your children on, but not a bad little handy camera for the money.
