That first post is so old ...I imagine he may even have bought another camcorder since then!

Maybe you should just open a new thread or search for a more recent one with similar query but FWIW i think the camcorders he discounted as being big are the best for the job ( at that price point) in terms of low light ability and the ability to control audio input levels .
Saying that, even today they still cost more than £1000
For video recording of Music events, having an off board microphone or even separate audio recording is not an unreasonable idea
