The smaller the needle, the easier it is to get a finer line, if you don't plan on doing any fine lines, I wouldn't worry to much about what kind you get, I'd just stick to a name brand, something you can get parts for easily (which most are). I notice a big differance from going to a .35mm nozzle to a .23 nozzle! I can make a fine line with the .23 very easy, and I'm just beginning airbrushing. I've ordered a few airbrushes from
www.coastairbrush.com and they state the Iwata HP-C is the same gun used by Craig Fraser. I have one on order now as is and should be recieving it this week. I have a micron C, which has a .23 nozzle and it's SOO easy to make a fine line it's not funny, and then I have an eclipse which is kind of a pain in the *** to spray a fine line, but it can be done, but it can spray up to 2 inches I believe, and the micron can't. coastairbrush also offers a teflon "Solvent Proof" needle bearing, which if your using harsh solvents is a nice little bit of insurance for the brush. I've heard of guys using the factory seals and being just fine too, they just clean them real good after each use. Hope that helps, any more questions just ask, I'm sure someone will be glad to chime in, specially if I'm wrong 8)
