Inexpensive paint, gun worth considering?

When I first started working in a bodyshop almost forty five years ago I saw an old guy painting the hood of a snowmobile with spray cans, I commented on how nice his work was even though he was using spray cans. He told me once you can paint you can paint with anything. I’ve seen guys that can only use one gun and guys who only use one gun. Guys who can pick up a total pos gun and then lay down some beautiful work. All you can do is pick it up and give it a squirt.
