You didn't list your skill level with an AB so I will assume it is a first AB. I have had a Badger 250, 350 and a 200. I currently use an Iwata CR and an HP-C.
The Badger 200 is a good starting point. A single action, well made, dependable Airbrush. I had the older model that had 3 different heads(Large, Med, Fine). It is a siphin feed and you can use cleaned paint bottles to paint directly from. It is good from base coats to fine line work. For 15 years I only used the 200 and was well satisfied. I would gladly get another. You set a screw in the handle to adjust the paint volume and the trigger controls the airflow, simple as it gets. Goes for about $50 at Dixie Art Supply.
I have had compressors and have worn them out. A continous, adjustable, airflow is important. A regulator and a water trap are important. I have gone to using CO2 in a 20 lbs cylinder. It is quiet, portable, uses no electricity, has no moisture problems, more than enough pressure. Lasts a long time between refills($14).
I currently use acrylics mostly-Tamiya, Model Master, and Polly Scale.
