On one of his book tests you need a specific TYPE of book, and he gives you an example (that will work) which you can buy from Amazon or other big book sellers. The book is ungimmicked, and it is an extremely clever effect. The other book test (actually done with magazines) requires pretty much any magazine, which you can buy from a shop right before you perform the effect if you want! It's ungimmicked.
I've done a full indepth review of his DVDs, which is posted on my website. I also posted it here so you can do a search for it.
Good luck, the DVDs are worth the money just for the book tests, but the rest of the material is also phenomenal
