There’s a list here also, but it’s out of date as well. The fact that it’s less out of date than Brickbuildr’s is probably not terribly significant.

I had planned on going to the King of Prussia store this weekend and, depending on what they had, I was planning on buying several cups to fill specific needs for Greenberg and beyond. So if somebody can find an updated list somehow, please let me know.
