Paint gun recommendation

DeVilbus Finish Line is my recommendation too. I have used really expensive guns and for the price I love my finish line.

Great guns for the money. I have a cheap gun with a 1.8mm tip for primer but use Iwata LPH400-LVX eXtreme basecoat for base and a LPH400-LVB for clear at work.

Not cheap at around $500ea though.
