I agree that in the parameters of The Dark Tower.org $2,000 would be the price you would expect to pay. However take for instance the auction a little while ago, in which Rand sold his bound and signed copy, which was a gift from Michael and Audrey Whelan. With all the provenance the book held, it was unequivocally stated by very respected members here, that $1,000 or thereabouts was the price it was worth. It sold for $2,900 I believe.
There are a huge number of collectors that never visit this site, probably many times more than come here. To those collectors there is a different expectation of retail, which is proven daily by the sales that are made.
David I agree with you completely, but only in the confines of the forum we subscribe to.
