I saw these books for myself when I went to Kinokuniya in NYC. And, boy, let me tell you!! These puppies are big. Maybe twice the size of the first edition manga. They're not quite hard cover, but the covers are sturdier than the average manga. At Kinokuniya, these books were priced at $14.50 USD, and they tend to be a little overpriced (talking maybe $.80 or so...), so anything around that price should be fair. :] The analogy of these would be the special edition of Tsubasa manga vs. the regular. The special would have more features, more free gifts, more colored pages, etc. More goodies! They're worth it.
