Here we go again just been recommended an app called Impcat which looks quite interesting for different colour schemesTo add, I have two, one is a cheap one from Amazon for £20, comes with various needles 0.2/0.3/0.4. I got it as an airhose was about a tenner and this came with it so thought it would be a good one for just priming (although you can absolutely do it with more expensive ones). My other is a Cult of Paint Infinity which is a 0.4mm needle, I would not suggest using a more expensive one until you are comfortable with cleaning and breaking down a cheaper one (although they do have a few differences in parts).
Depending on your environment I would strongly suggest a respirator mask, I didn't use one for one session and had a massive headache. I also have a very cheap extractor unit which I don't actually use the extraction on, just have the box to spray in to currently. Note the fan is actually very good for the job but it is very loud.
Compressor wise, I started with a Sparmax...something that @roman59 has, but it had some cosmetic damage, which was significant enough I felt I should return. In the meantime I got a cheap one from Amazon, it had an issue with the pressure but I realised it was because the gauge thing with the numbers was a bit warped and that stopped the needle going past a certain point (it was working fine), I sorted that and actually it's really good so I am sticking with it for now.
I was actually put off airbrushing because I started with a cheap one (weighed a lot), so if you do go for a cheap one (not sure on any cheap but light ones) and its the ergonomics that put you off, bear in mind that ones like the Infinity are much more pleasant.
If budgeting do not forget the additional that add up:
Airbrush thinner (advisable even if using airbrush paints just in case), airbrush cleaner, little pot thing to hold your airbrush and can spray in to, flow improver.
Then there are things not essential but make life easier like the bottles with the necks so you can easily squirt stuff into the airbrush, small pointy cotton buds (that don't leave strands/fluff), one of the little pokey/pipe cleaner type kits.
