Master Airbrush Cool Runner II Dual Fan Airbrush and Compressor Kit with Gravity Air Brush with 3 Tips (0.2, 0.3 & 0.5mm Nozzle Tip), Compressor with Tank - Air Brush Kit for Beginners & Professionals

Personally, I always recommend this kit, deluxe version. You want to make sure your compressor has a tank to smooth airflow, and the G223 airbrush comes with 0.2mm, 0.3mm and 0.5mm tips/needles. The G223 and G233 (has a fancier body and adjustable needle stop i near-as-never use) are my work horses, and because I build cars, I bought a Procon Boy PS-290 for the 0.5mm fan tip to replicate the sprayers used on real cars. The Master Airbrush rebuild kit is pretty cheap, too, if you do make a mistake with it.

The elitists are going to curl their toes over me saying this, but for just a little more than the Harder Steenbeck the other guy mentioned you can get an airbrush and pump combo from Master airbrush. Plus if you decide to get better airbrushes as you gain experience the pump will continue to work fine. You really don't need to spend more than $200 for a okay kit as a beginner. This is the exact one I started out with and it's perfectly fine. https://a.co/d/07eD3EoZ If you do already have a compressor, or you just want to upgrade to a name brand brush that's still affordable I highly recommend the Iwata Neo. I've had good use out of it. https://a.co/d/0gc1cUgL
