Just plugging my copy of Magehunter that is up for auction on ebay: AUD$225 + P&P.
"An opportunity to purchase what is quite possibly the rarest fighting fantasy novel. As you can see from the pictures clearly a well loved, well used book! Minor creases on the front and back cover with moderate creasing along the spine (binding still perfect though). There is a very small tear on the front cover about a third of the way from the bottom of the book (if it wasn't for this I'd describe it as in good condition). Some foxing apparent on the outside of pages. There are some pen markings on the list of fighting fantasy gamebooks page however there are no other marks anywhere else in the book (including the pristine adventure sheet)."
Being brutally honest with the condition of the book, and there are pictures on the listing for you to make your own judgement!
