I thought Star Myth (I think that's the name) looked like Expensive Pink too in the pan, so I swatched them side by side. They are nothing alike; Star Myth is closer to Mythology but not as brownish.
As for MAP, I fell in love with Chessa. I love warm neutral shades; Arena is one of my very favourites and this is even better. Chessa isn't gold or I could have duped it too. It's orange but still neutral; I think it's my Jete but warm instead of cool. Indie Spirit is fine; I was planning on getting Swiss Chocolate (still might) so I'm happy to have a neutral medium brown. I don't know what your stash contains so you may very well have dupes; I only know that I didn't have anything like this colour. The MUA said that there's nothing like it in the line; can't speak to historical LE items or competitor brands.
I have All That Glitters, Gorgeous Gold, Patina, Sweet Heat, and a bunch of l'Oreal Infallible variants on gold/pewter/bronze. Nothing like this. Expensive Pink is well...pinker. Magnetic Attraction is pinker. l'Oreal Magnetic Coral is closest, but it's still not the same. This is a shimmery orange. I can't wait to try it with a deep green or purple as well as some deeper bronzy tones.
Oh yes - disenable. Right.
You probably don't even like orange. Or it will look garish on your skin. Or maybe it won't even look orange on you, but just fade into your sea of golds. Save your money, you know you need more eyeshadow like a fish needs a bicycle.
