Its about the same. I have a Badger Anthem, which is a siphon, dual-action airbrush with a variable needle opening which makes it useful for all sorts of different materials and projects from minis to large terrain pieces. I've run all kinds of paint through it and it is pretty clog resistant, but isn't especially good for small details on small 25mm figures.

If you are going for something nice, I recommend the "German airbrush" that Matthieu uses: Harder & Stenbeck Infinity. It comes with both a .15mm needle and a .40mm. Use the .40mm for bigger stuff and the .15mm for smaller projects like individual details on 25mm dudes.
