Not sure if this has been mentioned here before, but I just came across it and it has my attention.
I would definitely wait for the price to come down, but what do you think. The folks that have shot/reviewed it really seem to like it. And with its billet aluminum receiver, seems to be of pretty good quality. And originally exclusive to Cheaper Than Dirt, is seems it no longer is as I've seen it on other retailers sites.
The end of the linked video shows the speed at which this thing can shoot. Thoughts?
