If you look at bookfinder.com people are asking between £195 and £700 for copies depending on condition of the book and dust jacket.

People are asking higher prices for the signed limited edition.

Low hundreds should be achievable on Ebay you may get a bit more at a specialist book auction house, but then your likely pay slightly higher fees.

Personally I would go with a detailed Ebay auction with lots of pics and a high start price of the minimum I would accept.
