There are many good brands of airbrush. Badger comes to mind right off
the top of my head
You will find many-a-thread on the subject
of a good brush (starter set for a beginner, Which A/B? etc) You'll
find it varies from person to person & what purpose you'll be using
it for. general coverage, Camo patterns or, fine detail.
Others
will know more than I since I am a noobie to airbrushing
I currently have a cheapy single action from Harbor Freight and
am awaiting the arrival of a Badger 175 (double action) which a fellow
modeler is sending my way.
