I'm shopping for a digital camcorder that will mostly end up being used to shoot dance - some practice, some performance, some inside & some out. So pretty much the full spectrum of lighting & sound possibilities. Right now I'm thinking just of shooting more video to develop better dancing/music, but I can imagine also wanting promo video from this thing - both web and DVD.

What camera features will I want most? It feels like i basically want EVERYTHING, and I'm not sure what camera would have that.
