Well for those of you wanting to make the move to a double action internal mix airbrush i would say its worth it,the qaulity of my work has improved and im still learning the ropes,i will tell you to pay close attention to the quality of your paint,as i had some nato green(tamy) that was kinda old,well when i got to the bottom of the jar i noticed small clumps,i thought my airbrush had been acting wierd and it seemed like i couldnt get a good clean line anymore,so i starting backflushing with cleaner and different pressures and low and behold a litte clump of paint backflushed into my pot,after that it began working properly again,i much prefer an articulate camo pattern over the broad grainy stroke that my old single action external mix provided and clean up is much easier after an process is developed,i think it was billipe and airbrushlers work that really motivated this move and thank you guys for posting your work
