I personally use a Badger 200 that is over 40 years old. One of the things I like is that it is almost bulletproof. Only parts I have replaced are the teflon washers that seal the head area. Still on my original needle. It is easy to clean, simple to reassemble after periodic complete teardown for cleaning. It is not terribly expensive as airbrushes go. Newer 200s look a bit different but internally they are much the same as my old one. Have several friends who swear by them also.
Compressors are something else. There are real tradeoffs there. In some ways the compressor is a harder buying decision than the airbrush. Big question is how important is noise (or lack of it). If you don't care about noise, a small general purpose compressor from the hardware or building supply store is cheap and adequate- they start at about forty bucks and work fine for airbrushing. Quiet compressors can be very expensive- cheaper quiet ones lack a lot of features.
