If its for speedball then its not a bad gun, but if you like playing with your buddies out on private property so you don't have to pay the field fees and extreme cost of paint(At my local field its 15 bucks a hundred) id look into the tippmann c3, 50,000 shots on a 16 ounce propane tank compared to 2000 shots on my 20 ounce co2. And it costs me 5 bucks each time I have my tank filled on the other side of town. You can buy a set of 3 16 ounce propane tanks at walmart for 14 bucks, thats 150,000 shots for 14 bucks compared with 375 bucks I would have spent on getting co2, not even counting the gas to drive there. I'll have one of these by the summer for sure.
