What paintball gun should I get?

I am in a paintball team now and I was playing with a spyder pilot (I know, crappy) but i would do pretty good. I was looking to get a dangerous power G4 that looks pretty good for my likeing. I have $250 and my mom might be willing to double what I have. I am an all around player so i move a lot making me the one that mostly bunkers others so i would like a light gun preferebly but not such a small frame like the invert mini. So what gun would you suggest? What gun do you have and what do you think of it?
