Sony has tons of these (I thought Amazon did too). I've bought a few.
Edit* Oh and the Sony version of this is $38, just not sure if it has the same number of books. If it does, holy crap, Sony wins the price war for once!

*Double Edit It's missing the 8th book, but even then it's still cheaper than the Kindle set. Not the paperback set though I guess.
