I use the Ryobi 18 volt. It uses the same batteries as all my other ryobi stuff. It shuts off automatically when it reaches the pressure that I set it for. So I can turn it on and walk away and do something else. Jeff has the same thing, except it is Dewalt, they both work about the same.

I don't regret the things I've done. I only regret the things I didn't do.
