Not sure about the holy grail they are out there just hard to find. Now if it was a billy cart or a prototype then maybe. Arh the mark 1 fan mower. I reckon in its condition with all the extras it should come in (if the seller lets it go to the end)somewhere around the $4000 to $4500 mark. Which just again proves to me that unless I can find a job that pays around the 100k mark,that I will never be able to have one myself. Which doesn't make me happy as I'd love to have one. Or two.
