Are Grex airbrushes good? I was thinking about one with the pistol grip but I dont know much about them. Can they paint a varitey of widths and even do luftwaffe mottling? I have a iwata eclipse CS Plus and it's good, just looking for something to compliment it.

as far as the Iwata, are there different size needles and nozzles I can get for it? I'm not even sure what it came with.
