Before I start, I do realize there is another nail gun thread on this page, but I don't want to hijack someone else's thread, and it doesn't really have the info I need.
I'm lazy. Too lazy to frame an entire room with a hammer. So sue me

I am GOING to buy a nail gun. At least one anyway. Do nail guns generally shoot one type of nail, and thats it? Obviously there's got to be a range of nail sizes, but are there any out there (good guns) that will shoot framing nails AND finish nails ? That would be handy. If not, i have far less finish nailing to do than framing.
Are there advantages between air and electric? Pros, cons etc etc? What kind of price am I looking at, and who makes the quality guns for intermittent use? IE : once a month on weekends or something like that.
Do they come with special tools for removing nails from flesh? :D :D :o
