I also have the PPS system and it rocks, plus you may be able to save a few bucks by not getting the cup with the gun unless it doesn't come with one anyway? Seem to recall I saved $80 or so doing that.
correct, you can buy it with the pps adapter, cup and collar instead of the cup. Liners are cheaper on amazon, but possibly cheaper through your paint jobber if you have an account.
These guns are pricey $600-800 depending on source and options.
I like the star trek gun, but you are right, functionally they are essentially the same gun. I bought a gently used one to try it out, and shot color and clear. I will buy a virgin one with a 1.4 tip to use as a dedicated clear gun when it is time to do the all over paint.
