I like the AK brand. I use their Real Colours more which are lacquer but the acrylics are good too. The line is extensive and sometimes the sets they put together are not as "job specific" as they suggest. ie there is a German panzer primer set but the colours are actually hull red, mahogany brown, dark brown and light brown. They are, to my mind, definitely an airbrush paint and to be safe I use the same brand of thinner as the paint when I have to. We aren't exactly slopping gallons of this stuff around when we paint so 2 or 3 400ml bottles of different brands of thinners isn't a disaster. Eventually you will gravitate toward a brand you're comfortable with and streamline your thinner inventory. Takom, Meng, Border etc seem to be using AK paint references quite a bit now. Matching brand to brand is less important than matching your paint to the actual colour you're trying to represent. That's part of the fun in research!
