To be honest as a collector, the pic totally amazed me lol I wish to have the same Ayu collection.
But the price is totally.. omg too expensive

. The last time I have counted how much it worth my whole Ayu collection so far, it was like 632 €. But it can't be compared as that guy's one because it's still incomplete. And I don't think I'll be able to complete it neither. And it's really too much for the whole collection imo.
If I were super-duper-rich I'd totally buy it

lol. And sell the extra copies.
I never get who buy multiple copies of the same thing :| unless they're first press and with different goodies, like (m)u.
