I started with a $20 air brush from Harbour freight, the trick is taking your time and keeping the brush clean and free of water. Hobby lobby has a 40% off coupon, you can jump into a system at a discount.
But you need more than a brush, you need a system. Airbrush, regulator and airpump/compressor.
If you haven't used an airbrush before then you have a lot to learn. Google how to paint a crank bait and follow the vide instructions. I bought a dowel rod and cut it into about 20 sections and practiced painting two or three patterns. Heat setting paint and base coat and clean tip...post those three rules up and when something goes wrong I bet you have missed one of those three.
Good luck!
