Paint gun for hobbiest?

I have been painting cars for over 40 years. I have mostly used Devilbiss guns. I Currently have two Devilbiss guns and an Iwata Super Nova. They all work great. My friend Mark saw the new HF Black Widow guns and bought on. They have been getting rave reviews. Just go on YouTube and see. Anyway, we are painting his 56 Studebaker Power Hawk now (actually I am doing the painting while Mark mixes the paint), and he wanted me to use the HF Black Widow gun. I am very impressed with it. Here are a few pictures of the results with the Black Widow gun.
That looks nice. I see they sell a primer gun too. I just like having an option for changing the tip sizes. I don't see any for that style. This gun looks similar and has different tip sizes included.
