Actually, my current jigsaw puzzle kick is due to online jigsaws I've been playing with. The above link has a zillion, all sorts of cuts. I also like the jigsaw puzzles at http://www.ucomics/games/. Some of the ones there have extra features, like all the pieces are black-and-white until you connect them to another piece, or the colors reverse.
