I have the California Air model 2010A. I like it very much. It is quiet, and because it has a decent size tank, it doesn't run very much. You can paint for quite a while before it cycles on, and when it does, it runs for a minute or less then turns off again. It's common to put 3-5 coats or more on a car body before the compressor needs to run. I've had it for two years with no problems, and it seems pretty well made.
