As a bookseller let me tell you that the absolute top price for a pristine copy of SSI is about $325. Amazon.com is trying hard to make up for the $40+ million dollars it lost last year. Amazon.com, like MOST booksellers, does not stock out-of-print books. When they get an order for one, they do a search. If they find what you want, they buy it at retail and mark it up to "whatever the traffic will bear". Do your own searches - free - at www.bibliofind.com - or similar out-of-print booksellers. I have no interest in this venture - I just don't like the way Amazon does business. Dick Ryan
