I am a complete noob to my airbrush, but it has been going very well for the past 6-8 months. After much research and asking on online forums, I ended up with an Iwata Revolution that is incredibly easy to use. It will even work with the 99 cent "multi-surface" acrylics from the local craft store for weathering my rolling stock and locomotives. That acrylic "multi-surface" paint sticks to everything I have tried it on, and it cleans up with water, at least until it dries. Just thin them with a little Windex and a little distilled water until the consistency of milk, test on a paper towel, and then test on something plastic first like a junk box car.
The Iwata Revolution isn't cheap, but it's also not going to bust the bank at $94 for a tool that will last almost forever if cared for. The large cup top feed Revolution is easy to use and easy to clean. The compressor is one that has a cooling fan in it for prolonged life. It was $80. It's also quiet.

I have the luxury of airbrushing an in air conditioned environment, so the moisture trap on the compressor is sufficient for me. If you plan to paint in any humidity, you will need an inline moisture trap too. They are not expensive.
Total cost $200 and I love this thing to death. I'd highly recommend it to anyone like me who has never airbrushed anything before. I also picked up the Model Railroader "Basic Painting and Weathering" book. A few YouTube videos taught me how to clean the airbrush properly, and away I went! Don't be a chicken like I was if $200 is in your hobby budget. For comparison, how much does a nice DCC locomotive cost these days? $200 compared to some other things we buy isn't that much really. I think fear of the unknown is a bigger factor, at least it was for me.
Cleaning station? 64 ounce fountain drink cup from the convenience store. Poke airbrush through the "X" hole in the lid (after consuming soft drink) and spray. Toss it out when done.
