Vallejo, are you serious? We do professional mini painting here, occasionally, and can't stand Vallejo. Their paint is too clumpy and thick.
However, we can attest to the quality of Scale75 and Reaper paint. They use a superior pigment and medium.
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?
I'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/
