airsoft guns are sweet! I don't have any right now though...I almost bought one at an army/navy store. They had an airsoft sniper rifle (with scope and everything) on sale for like 50 bucks! I was soooo tempted to buy it but didn't have the money at the time.
If you can save up enough get the gas powered (or even maybe the electric)! Otherwise you'll have to deal with ****ing a spring for every shot.
I'd love to have this one in gas/electric powered:
