BTW, I know you want an original, but if you can't find one, there are some nice reproductions available today.
They are all in about the $1-2-K range-- about the same price as a mint condition functioning original model.
The site, if you are interested, is: Deco Design: http://www.deco-dence.com/generic.html?pid=31
Except for the black color of the screen, they look pretty much like the real thing.
One just completed on 11-11-01 of $789. They seem come up for auction about once a month.
Good luck in your hunt.
