I decided to order one of the Charles Slutter "Lean Lamps" and found it for a good price at Retromodern.com. While there I checked out the rest of the site and found they had a pretty amazing selection, plus good prices. The home page is a bit messy, but once inside it's easy to surf their collection. Recommended.
I had a question for them and a fellow named Luke e-mailed me back promptly with an answer. Thanks Luke.

I'll blog it after it arrives and I have a chance to check it out.
