Hahaha, I never really thought about it that way! Good point about it not being very expensive for the paint. If I ever get my hands on a Falcon I'll go out and get the right paint. However, for my little $20 ships and figures, I like mixing paint not only for the sake of cheapness, but because I like mixing paint! I always find it very satisfying to mix up just exactly the right color from others. And I don't ever mix different brands or gloss levels (unless I'm experimenting on something small that I want a medium "satin" finish on), so there aren't any worries about messing up the paint's bonding ability or chemical properties. One day I'll get the falcon and it will be glorious.... only thing to decide (other than how to keep my girlfriend from freaking out when I buy it!) is whether to get the more appropriately scaled BMF or the easier to handle Legacy Falcon. Decisions, decisions!
