It's pretty much the same price as GW air and much easier/quicker to use with the addition of some different nozzle shapes and stencils.
This was my first find but lots of graf stores will let you select a dozen or 24 cans of whatever colours you want for a good price.
Many manufacturers have ranges similar in size to GW'S so colour mixing isn't really an issue.
