Hi I just started paintball, seems like a fun way to get outside for some much needed exercise. I have £300 to spend on gear and was shocked to see how much cheaper I can get markers for in the classifieds. I am looking for an easy to maintain marker that I can use for any kind of game, I have only plaid woods ball up to now but speed looks like a ton of fun. What do I buy and is it ok to buy second hand?
