[quote name='souNReAL']just to throw in my 2 cents, im kinda sure the books that are going for the absurd prices are the rare hardcover versions that were limited edition and only sold at various SDCC events. the info about the hardcovers was on one of Udon's websites
edit: but then again it could be some phisers trying to overprice the paperbacks for n00bs
ps, anyone know which is the best between the 3 street fighter books? trying to decide which is the best of the three
street fighter tribute
street fighter eternal challenge
sf20: the art of street fighter
the ones with the most female art is a plus

I own all 3 books. The SF Eternal Challenge book has been out of print for years and could be a bit pricey trying to buy it now. You are better off just getting the SF20: Art of Street Fighter Book since it has MOSTLY the same material plus it has SF IV art and interviews that are not in the Eternal Challenge book. However the Eternal Challenge book did have a cool character encyclopedia at the end of it but Udon is coming out with a separate SF encyclopedia book so you could just get that instead.

In regards to the SF Tribute book it is just that, tribute artwork done by comic book artists, deviant art people, etc. No official artwork, interviews or history info like the EC book or the 20YR book, but still a nice addition to the other books.
