I can't help you on the pricing of these, but wanted to say that they are very nice. I have not tried those CD notebooks but I just love them.
I bought some metal cases a few year back that came with notepads (cut down a bit) to fit inside. Made them for my sisters, and the rest just sit there, waiting for a home.
I think I will make them this year, for a sale at a friend's house. But those are hard to price as well. I think the case was a couple of bucks with the pad but I can't remember. So I was going to charge around $10 for them, all done up super pretty like.
