The funny thing is, i do have a $150 AEG (from wal-mart) and i enjoy it quite alot. And, again, (or maybe i didn't mention this) I'm not playing with elite players or anything. I just have a group of friends and only three of us have anything other than a pistol. (Mind you, most of us spent 50 bucks on them)
Just gonna let you guys know what i use, and see if its of any help.
DPMS M4 Carbine (250 FPS)
'Desert Eagle' [Cybergun] (200 FPS)
