Here we are again with paint guns. When I started painting last year I bought a cheap hvlp astra paint gun. It seemed to work ok but I out grew it really quick and bought a Devilbiss finishline II. What a difference!!! Now I feel I'm starting to outgrow this one. I'm looking at the devilbiss GTi Millennium. I've found it as low as $295.00. Its alot of money! Is there that big of a difference between the guns? Will I see a $200 improvement? I really don't want to wast my money but I really want to improve my paint.
