I thought buying a good air tank along with goggles was the smart thing to do.
I started playing paintball recently, when i get to college. I enjoy it very much, but it is expensive.
The thing you want to think about when playing is what you want to play. Wehn i play at school, its usually 5v5 speedball. very quick, intense, and people lay down a lot of paint. Other types of paintball are scenerio play, with buildings and such. You have objectives. and what not.
When i bought my gear, I got myself a marker from action village, along with my mask, hopper, CO2 tank, squeegiee (sp), barrel plug, and some oil to keep my gun in shape. I have an eForce EXT Piranha marker. My future upgrades are (if I can stop buying pc hardware) get a new N2 tank, and a new barrel for my marker.
