I still go with some friends from work about 3 times a year. It's really fun, but it can be extremely expensive. They have split paintball into two categories, woodsball ( playing in the woods, more like military clothing and weapons) and tournament ( expensive guns with computers, tournament jerseys, inflatable obstacles, mostly indoor). I use a gun ( DYE proto rail- about $500) with a automatic electric feed hopper that will feed up-to 50 balls in 3 seconds. The gun has a chip that will let you shoot semi-auto or full auto. They also don't use CO2 much anymore for air, it's mostly nitrogen. Paintballs cost about $60 for a case of 2000. That may seem like a lot, but my friends and I usually buy 4-8 cases to share when we go and play for a day. Each of us are holding about 6 pods (160-200 balls per pod) on us and that usually goes pretty quick. Don't let these prices discourage you if you haven't tried it or are wanting to go out for fun. Most places that are set up for paintball have really good gear to rent and is much more affordable that way. BTW, if anybody thinks that my gun is expensive, check out the DYE DM Matrix paintball gun and think of how many tools or maybe even a Festool you could buy. http://shop.dyepaintball.com/dye_am/marker-dm14-blue-polished-xx-edition.html
