I would save up your money and buy Japanese or European airsoft guns as opposed to Chinese stuff I own a TM AUG and a TM G36K
QFT. Bought one or two cheapos as a kid (About $100 each). They were fun, but not too much accuracy. I got lucky on a spring which shot a MUCH higher FPS than advertised, but the other was, well, it's money's worth.
Moved on to a Tokyo Marui M-16 vietnam edition... beautiful! Cost about $500 all said and done to get the FPS bumped up to a reasonable number, and ship to me, but it was worth it! I sold her before I left Hawaii, and was gonna buy a new one here... never got around to it though.
I've never tried airsoft... what is the typical range of the projectiles out of, say, a rifle look-a-like (as opposed to a short barreled pistol thing)? Accuracy?
With my spring 'sniper' rifle, at about 475 fps, (Higher end for casual matches) I kept it inside 200 yards. With the 6x optical zoom scope it came with, accuracy was... well... indoors without and wind, I could probably hit a person at 100 yards. 200 was just to shoot trees and general areas.
