Sudoku Players' Forum (clone)

Can anyone tell me where I can find a good source for really vicious, nasty sudoku's? I purchased the MENSA and Blackbelt books and have whited out the numbers to reuse the grids for harder puzzles I find on the net. This is getting old. Any ideas would be appreciated.

Although they have .ss extensions (since they're designed to load straight into Simple Sudoku) they're still only text files so you can easily open them with a text editor. None of them require trial and error to solve.

Would you mind telling me what you thought of the Mensa Sudoku book? I've been toying with the idea myself and just wondered if it was worth the money. BTW I'm at (The Times) Fiendish level, on a good day.
