I have a camera I used when giving lessons, but I have been looking at smaller options for ease of use.

Hey, that's pretty cool. I might get one of those slender bicycle crash helmets and that new "Action Tripod" and wear the Ultra HD camcorder mounted on a helmet while playing in Buffalo's pool tournament. I could see myself recording matching up with people and playing the match and putting that on youtube.

But seriously, the video quality is rather nice for a low light pool room environment.
thanks,
