I've had a Sears belt-drive, oiled, 20 gallon compressor since 1988.
Aside from woodworking, I painted 3 car (restorations) projects with
Sears stuff is cheap. I don't know how it would hold up under all day
usage. Mine probably has 30 hours on it total time.
If you are running power tools or spraying finishes you want a water
separator. An inline oil mister is good if using power tools. And above
all, get a 220 unit if your house is wired for it. The units run much,
Calculate capacity (ie., hp needs) by matching the highest air gulper
in your tool box. Usually, that is an air sander. Paint guns use
relatively little. Impact guns are medium users. The new HVLP guns
don't even warrant a 220v compressor, so save money.
The nice thing about any compressor, whether it be cheap or fancy, you
can unbolt any component that fails and put on a new one. Such as the
pump unit, controller, motor.
The Grainger catalogue allows you to virtually build your own from
components. I have a small, diaphram compressor (110) my wife uses with
her airbrush art projects. But the big one pumps up my bike tires, and
powers my air ratchet on all car repairs, as well as furniture repair.
Sears compressors, overall, are pretty low quality. Have you considered
getting a used unit?
