For anyone that has ever thought about getting into paintball, the one that you have likely heard of is Tippman. The company is widely considered the elite in the industry and they offer several different guns including their popular Custom 98 and the Model 98. This gun, which I own and have used dozens of times, was the cheaper version and while that may scare some new players away, If you are considering this gun, don't be scared.
In all the times I have used this gun, I have never had an issue with the paintball actually exploding in the barrel or hopper, which anybody that has even played once knows can ruin your day. The model I use has had no enhancements made, but for the novice player that I am, that isn't a worry. It can be customized with a new trigger among other things if you wanted to have the fast-action trigger.
Overall, there are better guns on the market, but why pay more when you don't need to.
