I have an opportunity to purchase one of these at a very reasonable price.  From what I’ve heard, these seem to be very rare as not very many survived and were probably scrapped.  Does anyone know how rare these actually are and what would be an approximate value?  I’ve attached a link to a photo of another one currently for sale with what seems to be a sky-high price tag.  Any ideas or advice would be much appreciated.
