I got this one at Harbor Freight for less than $20. It is a dual action with an adjustable stop on the trigger. I only need to paint bodies, so a single action woud do me just as well. I was looking for something so I could do colors that don't come in rattle cans or to use water based paints. Since I mostly paint HO bodies the amount of paint needed is small, you use up more of it mixing and cleaning up than you actually put on the car. In the future I will try to do several cars in the same color in one day. Since the paint has to be diluted you get a lot of fumes when you use solvent based paints. That was one reason that I built a spray booth.
Someone said that they had problems with a Harbor freight brush, but mine works fine. I added the trap and regulator, the air hose was also extra.
