I've been hanging on to these links for years because I've never been to afford the fancy metalwork ones, but would love to have one (hint, hint - do I have any rich friends? Demme!)

Here are two sources, one for inexpensive "ancient" lamps, one for beautiful metalwork reproductions. Unfortunately, I have no link with either one. Just in time for Saturnalia!
