This is the exact compressor and airbrush I used when I started. It is ....usable. It's good for you to get a hang of taking care of an airbrush and painting in general. Get this, use it to do a few kits. If you really like the hobby and would like to commit... then consider getting a better compressor and airbrush.

Better compressor would be something like this compressor with a tank

For airbrush, it gets expensive pretty quick. You can stick to the shitty airbrush first and once you got the technique down, try upgrading to slightly better ones... maybe the madworks airbrush or the procon boy..
