It is funny how the common absent figure in all our lists is the Destoroyah Evolution Set.

Well, or sad I suppose. No matter how you slice it, I don't think that set was received nearly as positively as it could have been due to the price and the redundancy and uselessness of the crab form. I think the size of the Aggregate was fine but I forget, while the fantastic turnout of the flying form wasn't enough to make up for the shortcomings of the set.
Mandarake has been a bit ridiculous about the Garuda set recently. The most recent one to go up was listed at 20000 yen! At least AmiAmi hasn't exceeded 15.6k yet.
