Toshi - My experience is with mostly Paasche and Badger airbrushes, Now I only use the Badger line, I'm completely happy with their performance and durability. I did have and use an Iwata Neo, siphon model, which did a nice job but had front end components that left me a bit less than confident about longevity.
One thing to remember about compressors is the noise factor, some can be quite loud and annoying to you and others that may be nearby. A diaphragm model may produce a slight pulsing, I found it easily controlled with a longer air hose, a large water trap would also help. I have no affiliation with Badger, just a customer, but I find them to be durable, easy to care for and to produce a good finish. many models to choose from.
The 200 NH is a simple and reliable single action model, quite inexpensive and capable of producing very good finishes. The 100-G, gravity fed double action is my favorite Badger, I use it for most of my camo finishes and it blends the color separations quite well. There are of course many other air brushes of very excellent quality, capable of producing finishes that are pleasing to see. Quality of service, ease of use and durability are all things to consider, depending on the use you will put it to.
Many times folks have bought an air brush and found it did not please them, then they moved on to others. For that reason I recommend making the purchase of one that is not a top line and very expensive model, Badger has several that are available for $60 - $80, you might well be very happy with it, if not and you move on to something else, you haven't broken the bank with a $200 type. I don't think I know anyone that only bought one air brush, then used it exclusively for the long term.
Good luck with your search, remember to do lot's of research and read reviews.
