I am not going to comment on the issue of re-printing the pricing info of other books, however it seems that people are overlooking the that this guide has a level of original infomration as well, specifically a listing of auction pricing ranges. This is where a book like this will shine. Show what these sell at in the real world rather than an estimated book value.

OK, I lied, I will comment on that. I might suggest that William leave out the other information. Legal issues aside, if he gets permission then great, otherwise I wouldn't do it.

If William is tracking the ebay, jackpot, club, auctions this alone would be a worthwhile guide.
