I do not believe that these ejector units are rare. We had the double row version in a fumed oak F-2, which we sold 2 years ago. If I would see another one, I would not pay a premium for it. I view these ejector units as clever gadgets, but with no real panache. On the other hand, we love the satin walnut Mignonette (Late) in our collection (similar to the one in the ebay auction) But collectors do not place a premium on this machine, so there you go . . . .
