I just found one at an antique mall here this past weekend and I put it on layaway. We don't find them here too much, and if they come up, usually the owners are asking way high $$ for them. Mine was pretty reasonable for it's condition...very good, and moderate price.
There are literally hundreds for sale on ebay at any one time. I wouldn't worry about them disappearing any time soon. And it seems the prices are coming down some due to the economy. Many are selling for a little less than $200, which is less than even a few months ago. I've been watching for about 6 months, and this is my observation.
