Does anyone ever play Paintball? Or take your kids Paintballing?

This game is a riot and I've gotten sucked into by my 10 and 13 year old boys. We were at a game this weekend and had a lot of fun. (In spite of a few guys who think they're trying out for the Michigan Militia). They never had anything like this when I was a kid.

I've got some questions for anyone who knows their stuff about paintball guns and equipment. If you can help me out I'd appreciate it.
