This is the bestthing out there in my opinion.
Then you will need a compresor unless you have one you use for pnumatics If you use a big one for your show, you can use that for make up you just need to put a regulator and water trap on the line. Or you could get a small airbrush compressor (your big one works fine)
here is a good model
yeah thats another set that comes with another airbrush, but can never have to many in my opinion.
I have an airbrush make up DVD coming out for haunts in march and I will go over setting up your make up area/ room .
good luck and start airbrushing! there is no faster way to do make up, i have about 60 make ups to do in an hour and a half it would be very difficult with out an airbrush set up.
