Mostly for target shooting in the basement, and for lugging up north every once and a while. Under 500 FPS and under about $250-300. I'm looking for something that isn't too loud, and is of decent enough quality to last a year or two until I have a chance to get my pal. I've narrowed it down to the following brands and models, with the Diana 21 Panther currently topping the list. In no particular order, what I've been considering: Diana 21 panther, Umarex Surge, Ruger Air Hawk .177, Benjamin .22, Stoeger x5, Gamo Hornet. Any other brands would be greatly appreciated as well.
