Airbrush advice needed!!!

I have been a modeler for several years, but I am new to the world of airbrushing. I am in the market to buy my first airbrush and compressor. What should I look for in an airbrush? What is the difference between single action and double action airbrushes? What are the best brands/features? How about compressors? What features/brands are best? Thanks for your input.

Asking for help in getting a brand of Air Brush is only slightly easier to figure out than posting a request as to what denominatin you should join. In many forums, this topic would bring about a great number of posts pushing their brand.

I won’t tell you what brand I have, though I am very happy with it. But I will say, get an internal single action brush. In model rail roading you really don’t need the sophistication of the double action - quantity of paint and air outflow.

Internal air brushes give a slightly better fine coverage than externals. I will let others flog their brand.
