It is expensive I grant you. Did you know the ammo you buy for about 140 for 2000 balls or there abouts they buy for about 29! That is a totally ridiculous and greedy markup. However if you have your own kit (marker, gas tank, face mask) and live on a farm (or have a very big garden!) you can play for next to nothing! As compressed air or CO2 are in expensive and you can buy your ammo at cost price. Also, if you have your own stuff, some places also have "drop in days" where you can just turn up and play for 20 and you bring your own ammo and they give you all the compressed air or CO2 you need. Oh and if you have some thick clothing it really doesn't hurt that much.
