I think my last post got deleted, perhaps it was in the wrong area? If you're going to delete this one can you let me know why, admins?

Anyways, what my original post was in regards to was the Signed/Limited/Numbered first edition of "The Bourne Ultimatum" by Robert Ludlum. I haven't seen any offered or sold anywhere on the net, and I was wondering if anyone knew the approximate value of this book?
