I've only had my 2240 a couple of weeks but it's easily powerful enough to reset targets, and accurate enough (even with the bog standard iron sights) to be fun. I'm not sure they can be beaten for what they cost, and then you can mod them so much that it gives you something to do when you can't shoot.
