I have bought from several companies online and all had great service except National Paintball Supply. They were out of a couple of things that I ordered. I called and e-mailed for 2 months to no avail then after about 3 months they arrived in the mail. I was pissed. So I would definately stay away from them unless you are sure they have what you want in stock.
Yay though I walk through the valley of the shadow of death,
I shall fear no evil, for I am the Baddest Mother F*ck*r in the valley...
