Hey Kelly. I was in your seat not to long ago. Driving down the "omgFPS" road. Well it turns out that FPS is nowhere near "the end of it all". Just keep in mind that for most outdoor fields, 400fps is a LIMIT and not a GOAL. A high quality gun @ 300fps will shoot just as far as my 360 G&G.
Make sure to buy something that you aesthetically like, because in the end you'll spend lots of time with it (hell, who would date an ugly bitch because she shoots hard?
I bought something before getting AVed. I wont say I regret it because I like my AEG and the way it looks, but it wasn't the smartest purchase in my life.
Anyway, I know I didn't, but I think you should wait a bit and see whats availably around
