Looks like Vallejo takes it so far. Curious if what people are looking for is more akin to "pick 5" of a set of colors or a packaged set of some basic colors?
NausI'm really happy I found a shop here in Baltimore that stocks the whole Vallejo range, I haven't had to scrounge around on Amazon for model air in specific colors for a while now. They ship nationally too: http://www.competitionminis.com/
