None, you won't be using this long enough to get an upgrade.
Three words: It. Doesn't. Work.
Well, I don't want to sound like some guy who just got beat in a match, and is pissed at his gun, but... this thing sucks. The first time I played with it everything went pretty good, the accuracy was off though. Second time I played, the paint dropped after about 30 ft. After I left the first round, I was sitting in the back of a car with my gun laying on the seat, when BANG! the expansion chamber blows up. The stupid o-ring got blown out by the pressure. After much debate, my dad and I came to the conclusion that we needed to adjust the regulator screw, that somehow it had gotten loosened. But other than that, we were sure it was a good gun, so he got one too. First time I used it, no surprise, it blew up. And that time we had gotten a pressure gauge, so we knew the pressure wasn't 'too high'.
Conclusion: don't get this gun. If it would work, it would be a good gun, but with two guns BOTH blowing up in the same place, you know it's not just one model.

i agree the thing doesnt work, but the whole story about it exploding sounds like a lie. Expansion chambers just dont explode. If it did, u would have been seriously injured because of the shrap. AND this comment goes out to all the newbs who embelish stories n such. this site is for good reviews but not for lies.
