MagCloud - New Print-on-Demand publisher, they only do saddle-stitched, color, in letter size but for that configuration they're cheaper than Lulu. Currently in Beta.
Tales of the Ink Knight - Where I found out about MagCloud
The Uncarrot Tarot - WTF?
Planet Koozebane - I dare you to use this in your next sci-fi game.
Hack/ random dungeon generator - Probably my favorite online random dungeon map generator. It doesn't do any of the stocking for you, though.
