If you have a set of nozzles from your old Aztek, you are just $75 away from getting their newest metal version body. You won't find it anywhere else but directly with Testors. I own a Talon, but it is just gathering dust, used it a few times and went back to the original box. Good AB, but I'm too used to the Aztek system.
This Mig 21, just fresh from the oven. Done with the Tan Nozzle free hand. All paints were ready in their respective gravity cups. I just flush the nozzle with alcohol and switch color. Whatever saves me time on the workbench, I'll go for it. Just my 2 humble cents.
EDIT: Mike, that's my main complaint with the Talon. Poor balance and ergonomics.
