I'd say skip the kit and get the compressor and airbrush separately. A decent compressor will be a good investment. I have this model from Master Airbrush, and I like it. It's very quiet even when running, my wife can be in the next room and it doesn't bother her at all. Price isn't crazy either.

I agree with the recommendations for the 105. Later, once he has the basics figured out he can upgrade to something else. He will need a respirator, and a spray booth would also be an excellent idea. Booths are available in many different sizes and prices, so you don't have to spend a ton of money to get started. You can even build your own if you have the tools for it, it could be a nice father/son project (I have some videos bookmarked on this I can share if you're interested).
