I have an iwate eclipse hp-cs i believe it is. I think it's the greatest thing ever!!! Excellent control large cup. Easy to break down and clean. Parts are readily available. It is a dual action which is great! It can damn near go from a needle point to to a nice wide spray! I also have an iwata compressor which is also an excellent piece of equipment! I forget what model right off hand, however it is super quite variable psi has it's own water filter and a holder for the brush right on top. I also put the pistol grip water filter on my air brush double protection!! Anyway thats my opinion. I'm sure you'll get a few differant options.

 

I'm looking into getting an external mixer airbrush. I like the idea of easier cleaning as well as faster on-the-go paint color changing. Not sure what brand to get. Still looking into it.
