I just used an LPH-80-102G to spray two planes. It is a very high-quality paint gun, and it has a very nice spray pattern. Instructions recommend using 13 psi and I found that it does have less over spray than the "touch up" gun I have been using. Swath of spray seemed to be 3 to 5 inches.
My only problems were the three control knobs turn easily and would change setting by me inadvertently moving them while holding the gun. A couple of times I stopped, wondering why it is not spraying good, to find my little finger had nearly shut down the air control. It is a small gun and all of that is fixed by familiarity, paying attention, or having smaller hands.
I never had dope dry and plug the spray nozzle, even when letting it sit for a few minutes when moving parts around. Seems that was a real problem with the old gun.
I am not a painter and can't claim the finish was better in my hands than the old gun. But it did use less air and had less overspray and was fun to use.
I can feel the quality of the Iwata when I hold it and that helps bring joy from the task. I have heard may arguments about a cheap wrench doing the same job as a Snap On. I have a set of Snap-On tools I have been using for almost 40 years. I still enjoy the feel of them every time I get to pick one up.
My old gun was 70 dollars 30 years ago. Harbor freight sells a similar touch-up gun now for 29 bucks. If you are on a budget, get the Harbor Freight one, as it will be better than no spray gun. I don't recall the price of the Iwata, but it is a jewel.
I like it. Your mileage may vary.
