You're going to find it difficult to stick to just one paint brand. Tamiya is good paint, but the color matching is lacking unless you're into WW2 Japanese subjects. Or when they do a new 1/32 aircraft; they usually do the needed colors for it.
MiG, Hataka, AK, MRP, and many more. There's an embarrassment of color lines available today. You may want to consider AK's Real Colors line. Behaves similar to Tamiya, and has WW2 and modern color matching. Use their thinner, though, for best results. Also like Tamiya, not great for brushing, though, without a retarder added.
