If your not doing a restoration, and are looking for reasonable cost paint of decent quality, you might try this company. I have been using their products for a couple of years now. They ship direct from their shipping entity The Coatings Store, the paint shoots well, even for a backyard hacker like me with a hobby Eastwood hvlp.
