Any suggestions on a cheap but decent (say sub $400) video camera to purchase for doing home video and snapshots? I'm looking forward to having the iDVD software so that I can make and edit my own work. Nothing professional, just nice home movies, etc. A couple of other specific questions: 1. Do I need to go with a digital camera? 2. If I do, is it possible to use the camera itself for video confrencing?
