I bought the book but haven't really looked at it much because I'd like to play it before I read it. (Spoilers, etc.) A few of us were discussing the "lose your magic items forever" aspect of ToH that apparently was done in some of the pre-release convention versions, and I never liked that about the original ToH. (They said that they played ToH in a 4-hour time slot, so the adventure must have been chopped down significantly.)
