This forum thread is the point of entry for links, discussions, and questions about where to buy tools for working with chocolate.
Please do not post links to sources for chocolate or sources for chocolate related items (such as books, t-shirts, etc.) There are separate forum threads for those.
In addition to all of the suggestions following I can recommend Pastry Chef Central and Bridge Kitchenware. I bought a copper sugar boiler from Bridge that was on sale (about half off) and it's my favorite thing to make caramel in - plus, it's just beautiful to look at.
