Need some help!

I've always wanted a copy of the Easton Press' The Silmarillion; but eBay listings always have new/sealed copies, and nobody seems sure of the printing status.

Whats with the printing history of Easton Press publications? In particular when did they first print The Silmarillion?; when were subsequent printings?; and how are these differentiated on the copyright page (or otherwise)?

Any help much appreciated. Information on any of the Tolkien Easton Press publications would also be welcomed. Also, has anyone bought the CoH Easton Press yet? (and have any information/comments on it?)
