What do you really need an air compressor for in a home shop? If you look at things objectively, you might blow things down, run a paint sprayer, or a brad nailer. I have been told you shouldn't use compressed air to clean your machines, because it blows debris into areas that are inaccessible thus causing excess wear & tear. Unless you have an industrial duty compressor you can't run a die grinder, and for the most part you can get electric tools that do the same as air tools. I.E impact drivers, die grinders etc. I used to have a large compressor, and I rarely used it. I now have a small compressor that suits my needs very well, but I have a small shop with small needs. It is all relative......
I agree, but I want to do some spray painting of parts on machines I need to restore, and I want to use the Porter Cable nail guns I bought at an auction to put some paneling in the laundry area (I know, an excuse to play with some toys). The sprayer and nail guns need intermittent pressure.
I am reading and digesting all the comments, and so far, it seems the GMC Syclone, (http://www.amazon.com/GMC-SYCLONE-Ul.../dp/B0038MWDXY) ugly as it is, will fit my needs for $225. The tank isn't big, but I don't have much room. Yes, I could look for a used Champion, but do I need yet another project when I have machines I haven't yet restored to operational? At 58 decibals, SWMBO won't complain too much. Yes, it is oil-less and therefore won't last past 3000 hours, but that is a lot of time to an occasional user like me, and I don't want to mess with oil that I have to clean up. Oil can be noisy too. It draws 8 amps which means my existing wiring is good (12/2, 20A lines). It will fit in a corner.
