Hi John.
It's good to hear you are having a good life from that C-H compressor so far. Is it the "Quiet Compressor" model? If so then you are fortunate.
I thought I heard someone say on the airbrush forum that I attend that C-H has improved that little compressor but I can't confirm that.
I am not familiar with the Home Depot compressor but it may or may not be good quality, it depends on who builds them.
I have never heard any negatives about any of the Sears compressors except maybe for being noisy which all industrial compressors pretty much are. I have a Craftsman oiless 1.5 hp model with a 12 gallon tank that I have had for nearly 10 years and it has performed flawlessly despite using it at 60-80 psi for several hours a day at times. The bigger models that are great for running impact guns and such around the home seem to last a long time due to the fact that they run very little for airbrush use with such large tanks on them. But if you prefer a smaller compressor then the little one I mentioned before will probably suit your needs well. It is this one:
It has a 1 year warranty which you could extend for another year for $18 if you want, although I have never had or heard of problems with the Craftsman line of compressors, but that does not guarantee it will last.
It does have a fairly small 2 gallon tank which is going to cause the motor to run a little more often than a bigger compressor, but at the lower pressures we spray at with airbrushes it will probably only come on once or twice during a painting session.
This one for $169 might be a good choice too as it has a 4-gallon tank with a 2 hp motor, but then you are starting to get into the price range of quieter airbrush compressors like the Scorpion II and others.
One thing nice though if you can stand the noise is that these compressors can be used around the house to fill car and truck tires, run an impact gun a limited time, a nail gun, or whatever else you may need it for.
I don't know who builds the Craftsman compressors but I believe my older model was built by DeVilbiss for Sears and they have a good history as a manufacturer of quality compressors.
I hope this helps somewhat.
Mike
