Airbrushes
Harder and Steenbeck Silverline Evolution 2-in-1
Bought November 2020. This comes with 0.2mm and 0.4mm needles so it can do very fine work as well as more general colour fills on models.
Neo for Iwata TRN-1
My first airbrush and incredibly comfortable to use, being a pistol trigger design. This has a 0.35mm needle so it is a balance between fine and general work. For some reason this airbrush gets dry needle tips very, very easily. So it needs constant cleaning.

No-name sidefeed & suction airbrushes
I got a pair of no-brand airbrushes; one side-feed, the other suction (which I don't use). The side-feed isn't bad, not particulary fine, but it's good enough to do all of my heavy duty work (e.g. priming).
Other tools
Compressor
I use a cheap compressor from Amazon. It has an air tank and pressure valve. It was cheap, but works great. Usually I have it set between 15-30psi. The compressor runs for a couple of minutes at a time, and if you are using the brush more-or-less constantly, you'll get a couple of minutes between the compressor running. So it isn't silent, but it's quiet for periods of time.
