If people are expecting to buy guns around 100-200 price range, i'd suggest you be prepared to spend 100-200 more upgrading/replacing the gearbox. It's sort of like a luck based game, you can get a really cheap AEG and have the motor last around 15000-30000 rounds (If your lucky) before the motor breaks or your piston gets stripped, or you can spend 300-400 on a AEG and have it last only 4000-5000 rounds (If your unlucky). The very best possible AEGs are ones built with a good durable motor, piston, and 8mm-9mm metal bushings and sometimes even then it'll break right out of the box. It's all part of the sport of airsofting.
