Just google “video camera review”, and do some reading. Check lots of sites… Everybody will have their own opinions… Many will even try to tell you that you shouldn’t buy anything but and HD video camera. Personally, I wouldn’t recommend an HD video camera just yet. Still to expensive, and not enough software and playback support as of yet. It’s getting there, but I would still wait.
From all the reading I have done, I would recommend a MiniDV camera. They offer the best options for storing/saving original video files, and are easiest to edit and convert to different formats, with least amount of quality loss.
