The JG guns are Decent. My first m4 was a JG lasted 4 seasons before the front of the gearbox cracked in the winter. All I did was change the barrel and hop up. If it's possible I would suggest saving up a little more money. You are going to want to buy some batteries (at least 2 if you are going old school) if you go lipo then you'll likely only need the 1 battery and a decent charger. On the up side good lipo are cheap compared to good nicad/nimh
A JG m4 of some sort for under 300 bucks should last a decent while and will take all the aftermarket parts when something breaks.
