Help locating paints and color suggestions.

Hi all.

I need some help with finding paints online (or in the New Braunfels / San Antonio TX area). The local Hobby Lobby is very limited with their paint selection.

I have purchased a Gunship grey but something tells me that its not going to be a correct match for Panzer grey. Does anyone have an links to good deals on the internet for acrylic paints that I can use in my airbrush for the common German colors?

Also, what other colors should I stock up on for my German armor?
