Airgun Pistol Suggestions?

An Ataman AP16 is about as good as you can get IMO. Fills to 300BAR, is regulated, and gives a decent shot count. Does 12-13fpe right out of the box. I modified mine to be able to dial the power down and back up with the turn of an Allen key. Very loud without a moderator though, and not cheap. But it's built very well and has killer accuracy.
