I have a Devillbiss Finishline lll for an all around gun and when I don't want to do a full blown cleaning job on my Iwata. You can get 4 different tips and I have all - and have used that gun for everything from lacquer primer (yuk!!) to polyester spray filler and everything between. Works great and have ~ $200 invested for a quality gun. The HF purple guns - work well for some folks, but not me so will not recommend it - it's also, an air hog which means lots of overspray which means wasted paint - my shop has a fair amount of paint speckles from my experiences. Astro also makes a fairly good gun in the $70 +/- range.
