Need Help:

Need suggestions for a light weight, mobile, HD video camera. Something that takes good video and is easy to transfer to computer for upload.

Needed to record concerts, etc. Would love certain features like zoom, USB connection, auto playback, etc..

Thoughts? I've done some research but would like to get your opinions.

Price plays a big role, I do not have a school budget for this so it'll probably come out of my own pocket... the life of teachers.
