If you're a begginer airsofter looking for an inexpensive good gun, these ones are the best I've seen/used for the price.
First, I want to say, for all you more experienced airsofters, when you see these guns, you'll think, "What the?! Crosman?" But they are picking up their game, and they are making better and better guns for good prices. (For begginers.) And I've used all of these. I was surprised by their quality and performance.
Spring Pistol: Crosman P9 ($40)
Spring Rifle: Crosman R39 ($35-80)
Shotgun: S34P (sold by UTG and Crosman) ($50-120)
Gas Pistol: Crosman Airmag C11 (at least I think that's what it's called...)
