I have a Porter-Cable air compressor that I use once a year to blow out my sprinkler system. The only power tool I own is a Ryobi electric drill with a cord because I use it so rarely that the battery would always run down on my old cordless drill.
When I bought my house 10 or 15 years ago and was doing a lot of home improvements, Ridgid had the contract with Emerson Electric that Craftsman had abandoned. I have no idea if that's still true, but my oldish Ridgid power tools have been great.
I’ve got some old Porter Cable and some newer stuff. The newest stuff was one of those 5 piece tool sets, drill, flashlight, circular saw, etc. I’m on the second pair of batteries and still going strong. The old stuff is like a tank.
