I've been using this 5HP 20 Gallon Coleman for 7 years now I'm happy with it. It's portable and runs all my air tools including my HVLP paint gun. (you'll need a moisture filter/trap) I've never seen a compressor yet that's not noisy. You will find that the tires on your vehicles will last a lot longer if you own an air compressor. You tend to keep them at the right P.S.I.
Here's my setup.
