I got started pretty easily. I bought a double-acting airbrush for like $15 on E-Bay. It's the same as the name brand without paying for the name. The same with the braided hose and filter. So I just use my compressor for airing up tires and larger paint sprayer.

As for getting started look up Expert Village on YouTube. Mike Royall does the videos. They have a ton of how-to videos from simple circles to bubbles, stripes, stipling, you name it. At home I have a whole folder of the videos I saved and used to practice along with. I find coupons for like Michaels and Hobby Lobby etc to get the paints fairly reasonable.

So you can get going fairly inexpensively.
