i love paintballing but i dont get to go much, the only thing thats expensive about paintballing is the paintballs, the paintball gun is a 1 time cost, and could be upgraded with a scope, auto trigger, sniper barrel etc, the paintballs are expensive, really expensive, like 25 bucks for 2000, which seems like a good deal, but when your done your like wow that went fast i just spent 25 bucks...
and the co2 is like 4 dollars for a 20 oz, a 20oz is good for about 1000-1500 shots i believe, i have 2 20oz, 1 9oz, and 1 16 oz.
guns specs:
spyder xt aggressor (newbie gun, im new to paintball but i love it)
16" blue sniper barrel (forgot the brand)
*no upgrades yet ie: auto trigger
*
some tips i learned on my own:
1) dont wear white
2) increase your velocity on your gun or your paintballs will lob out
3) wear camo, not bright green etc (for woods)
4) GRENADES ARE 1 TIME USE ONLY ps. dont stand near them
