I got this one in.22 at Walmart for right under a hundred. Awesome, accurate and hits pretty hard. I would never entertain the thought of a pump or Co2 for any number of reasons. The single stroke allows the ability to **** it and leave it in the corner virtually forever without loss of compression. You never know when you need that quick shot.

Another option is a .22 rim fire shooting short CBs. They hit a lot harder and are quieter than a pellet rifle. Only catch is that you would need something aside from a semi auto as they don't have the power to actuate the action. They also cost a little more.
