Thanks all. I will still be using a lot of screws. When I'm working by myself, it sure makes it a lot easier to square things and tack them together with a nailer. Then I finish with screws.
There are a couple of Bostitch and Cable-Porter finish/framing nailer kits. I'll probably pick one of them up on Friday when I go to town.
I don't know what my old "portable compressor" weighs, but it doesn't fit in my tractor loader bucket. It is a vertical unit on wheels, but it is only somewhat portable, even in the shop. I'm thinking it goes about 200 lbs, so it isn't real portable. I almost never use it anymore. I just hate to get rid of it, as it is good for painting. The impact wrench is real handy once or twice year, and the air hammer was invaluable when I removed a bunch of ceramic tile. I've still got one more bathroom to go.
Again, thanks.
