The only one that comes to mind is the Oskar and Macha waltz. I know they have a bunch of limited, discontinued ones that are in demand like cerises, cherry blossom and graffiti. But those pop up on ebay on a weekly basis. So they are attainable. What is the top bag that is limited, and hard to find? I know they make exclusive bags every year but I cannot think of any other that was so sought after and extrememly hard to find except for the Waltz Oskar and Macha Waltz. Are they any others?
