Side note on my airbrushing kit:
I’ve had an old Passche single-action, that's being going strong for thirty years. It's easy to use, but a real pain to clean. The colour cup has to be taken out every time, using an allen key. Quite a lot of paint gets wasted changing between coats inside the cup and needle. It’s also more clunky to use.
Last year, I treated myself to an upgrade with a dual-action Iwata Eclipse. It's lovely to use, and super-fast to clean. A quick spray of thinners and I'm on to the next coat. The whole experience of painting has changed since then. In a good way.
For an air supply, I use a dive cylinder. If noise is an issue where you live, this will solve all your problems. The air from it is dry and clean, and it's totally silent. I use a compact 5 litre steel tank and a second-hand first stage with the demand pressure adjusted down to about 150psi. It doesn't need to be new and high-tech, I'm not trusting my life to it. An adjustable in-line air regulator drops the pressure from there, down to whatever I want.
