Not to try and be disagreeable but I have to disagree on getting a big huge air compressor. He mentioned he's not wanting to use air tools most likely, a small compressor give the option of moving it and for blowing the crap off a battery terminal you certainly don't need a 100gallon tank. If you are using it to sweep out your garage then yes. Or run rotary tools from it, yes. Nailers, staplers, etc don't require much of a compressor. Painting, different story. It depends on what you are looking at.

Also, why spend 800$ when 100$ will work fine? With my pancake compressor I've reseated the tire on my fathers 28hp tractor, because his compressor was stuck in the shed and 300ft of air hose wouldn't reach to the tractor. I run nailers all day long off the sucker. Buy for what you are using it for.
