Protoyping Resource Page

So yesterday I was having a discussion with some people who were looking for wooden trains and pirate ships for their prototypes. I pointed them at spielmateriel.de (Mayday Games also has trains, but no pirate ships).

And that got me to thinking. I have a personal list of go-to places for bits, but a central repository would be excellent. Does such a thing exist, a database or even a web page that lists links to good places to get cubes, meeples, and other bits for games?
