If you haven't seen them yet it's worth a click. They do some very cool work in not only stamps but dies and engravings. First I ordered a "CADY" stamp.
And check out the Chalco Stamp and Die webpage: http://www.spanglefish.com/metalstamps/
Little hand stamps like mine are pretty mundane compared to some of the other work these guys have done, click through their pages and see what I'm talking about.
