Best Available Sudoku Book

This is an excellent book in every way: its contents are the highest quality, pages are large and grids good size, the paper is strong and takes erasures easily. Mr. Longo's earlier attempts at difficult sudoku puzzles were unsuccessful, IMO. I breezed through "Absolutely Nasty Mensa Sudoku 1,2,3, and 4" and "Black Belt" 1 and 2 with no difficulty. But here you have 1036 (really!) difficult sudoku puzzles which are real challenges if you are at the advanced stage. It is the best sudoku book I have found, and I recommend it highly. And the price ("used" or remaindered) is incredible.
