Airbrushes are highly personal and subjective. They remind me a lot of baseball gloves and golf clubs and hockey sticks in that way. One person swears by one, and the other hates it and has another brand/model they prefer.
I also was not a fan of and sold my Grex Tritium. As an airbrush it was actually pretty great. But man, that pistol grip was not for me. Takes a lot more effort holding it 25% open than it does with a traditional airbrush.
Agreed, and that's a perfect example. To me, the Grex Tritium is the greatest thing since sliced bread. I have a far, far easier time controlling fine paint flow with the trigger in a pistol grip. I also started out with an Aztek A7778, and while it works just fine trigger control eluded me. Tried an Iwata (can't remember the model... sold it shortly after I got it) and while the trigger was better, I still had control and comfort problems. Just picking up the Tritium brings a smile to my face.
I still have the Aztek and use it quite often with the white .5mm tip to blast out primers and Future. No trigger control needed there. :)
As to the OP, if you don't mind the smell and fumes hazard (and rattle cans are much worse in this regard for most paint types anyway), you'll likely get more consistent results out of solvent paints like enamels or lacquers. In terms of prep they're 'easy mode' compared to performing acrylic alchemy. Thin it and spray it. With acrylics, you'll need to check the consistency of the specific bottle you're opening, filter the paint into the mixing jar to remove clumps of pigment, add retarder, add flow-aid, thin with future or acrylic medium, curse at it, clean the airbrush and adjust the amounts of the previous ingredients, curse at it some more, consult a barometer and relative humidity guage, adjust the temperature, then perhaps get a good finish. The next day, do it all over because the humidity has changed.
Bit of hyperbole there, and lots of people have excellent results with acrylics, but enamels and lacquers (Model Master enamel, Floquil, Mr Color, Tamiya with lacquer thinner, etc.) really are easy mode compared. In my experience, paint prep was the biggest hurdle in the learning process. When it comes to acrylics I'm still trying to learn it. Probably why I'm stocked up on Mr Color, Tamiya, lacquer thinner, and a good mask.
