Wayne, you can't go wrong with the Iwata Eclipse HP-CS. It's a great AB for the money. I have several of those, and one with the MAC valve underneath so I can dial down the pressure right at the gun, but that's not a big deal you can get a dial hook up adjuster for the line . . .
Yes, lately I have been getting the pre-mixed paints from COASTAIRBRUSH, and those are ready to go, although I will often put another drop or two of the reducer.
Remember to practice every day and you'll get the hang of it before you know it.
You are entering a whole new world of fun and possibilities! OH, and don't forget to invest in the best RESPIRATOR money can afford. Take your HEALTH seriously even when you are airbrushing acrylics.
Good luck and have fun.
