For those that want to venture into HD filming, yet don't want to spend the mega-bucks for a 1080i/p camera, Aiptek makes a great 720p flash camera. It's on Amazon for about $130. Buy it together with a 4 GB SD card for $14 more, and you're set. Here's the amazon link:

This is a great alternative if you're on a small budget, interested in making quick YouTube films, or don't want to deal with mini-DV tapes.
