These things kick ass! They range from $17 to $100, ammo is 5000 shots for $9, and they don't need CO2. The one pictured at the left is the one I own. It is spring powered, hand cocked, and comes with a 22 shot capacity magazine which slides into the handle. You can buy extra magazines for $5.97. There is a huge variety of them, including fully automatics, available from Cheaper Than Dirt.
