I have an oilless 20 gal that I bought because they were blowing it out at $49 in 2010. It sees a fair amount of use. The regulator went on it, but I bypassed it and used a nice locking unit from HF that was like $10. I expected it to die long ago, in fact hope that it does before I move, as I want a quieter oil version.

Echo above comments. For inflation use, I'd get the smaller unit, the 20 takes a while to get the tank up to 150. For tools, more air is better. To get any impact to really work well you need airflow, changing to the high flow couplings (I have them on most things and made up an adaptor to use on inflation tools etc) turns a useless 1/2 gun into a tool that will actually do things. Harbor freight calls these "automotive" type. They're expensive, relatively, and aren't in the bins but in blister pack. Going to 1/2 hose is even better, but its unwieldy in most home environments.

And their buffer, as mentioned above? Ace. I know folks in the auto body biz that use them, claim they're as good as a Porter Cable etc. Just don't lose the spare brushes.
