UL-approved, please! :)
Hi Cinnamon, are you still looking?
You might want to look at Pottery Barn - their serena Antique and rustic glass are both simliar, and less.
I'm ordering my pendants from LightingDirect. They are LightingUniverse seem to have the best prices on the web. I found several that were simliar at Lighting Universe with a quick search; you might like Progress Lighting's 5184-104 or ET2 Lighting's Starburst 20108-24.. And if you're willing to think about a little more elegant check out the Thomasville Roxbury.
