I read in the original post title "EX-21". I agree with Kevin, I would not go that high on a 16" and I agree the "Excalibur Limited Production Anniversary" does not increase value to me, but for a " pristine, hardly used one", 21" I may. The Ex is a fine saw. I'd want to run it first and check it out thoroughly at that price but if all is as it appears... it is a great saw and like knew ones are going to become hard to come by. Just my opinion not worth much, for sure.
