Are there any Web sites or other sources of sudoku puzzles that are known to frequently offer puzzles with more than one solution? If so, which ones do you know of that do this?

There is a list at Sudoku Players' Forums

Thanks, Jean-Christophe! Any more to add to that? The only site mentioned in that post that is still in operation is the free-sudoku site. Does anyone know which online services use their puzzles?

The only other ones mentioned in that post you referred to are either hand-held games or books (along with a small handful of isolated instances in newspapers and Web sites). I myself encountered several in the first volume of the "Sudoku for Dummies" series of books (I haven't gotten to the other two books yet).

I'm trying to find out which Web sites (in particular) routinely offer multiple-solution puzzles, especially those with a LOT of puzzles available, so that I can stay away from them!
