When my house was being built last year I used the contractors Porter Cable nailer for some quick work. The next time I was at HD I picked one up. I should have done it years ago.

I have fired five cases of nails with it and no problems. It sure does speed up the projects. Also picked up a finish nailer to help lay flooring. Just used that yesterday to build two trellises for the front of the barn. The right tool sure makes a difference.
