IMHO.
Pick up a compressor with tank.
Buy a GSI Creos Proboy AB. It is VERY similar to my Iwata HP-CS for half of the price, in fact I grab it more often.
Check out the Mr. Hobby line of brushes. Tremendous bang for the buck. Very similar in quality to Iwata, but typically noticeably cheaper at every relative level. This brush kicks ass for less than 100 USD: AMAZON LINK
A compressor is a compressor. Get one with a tank and a regulator and a moisture trap for as cheap as you can find. The only downsides on cheap compressors tend to be heat and noise.
Sigh…sorry about that. You have no idea how many times a week this question gets asked here.
I always recommend the GSI Creos PS-289 .3 brush here.. If it’s not available where you are then you can probably get an Iwata HP-CS which is more or less the same airbrush for more money.
For a compressor any of the generic AS-189 type units with a tank on Amazon here.
Get a hose.
Get an airbrush holder for you bench. Get a mask. If you’re spraying lacquers or enamels get a respirator and buy or build a spray booth vented to the outside.
