Although not on your list, I bought
THIS set and it's been great except for one thing... the 1.8 tip is too big but the kit comes with a 1.5 tip and it seems perfect for high-fill primer. The set you are looking at doesn't come with a 1.5 tip.
I bought my HVLP touch-up gun at Harbor Freight and give it two thumbs up. I've sprayed my entire interior with it and am very pleased with it... my painting stinks but that's not the gun's fault.
