As one of the Amazon reviews points out, there's a question here about how good the binding is and whether it can actually support active reading of the 1000 pages for the lifetime I'd ask of it.
On the other hand, $200 for a nice edition of the complete run isn't all that unreasonable.
I love hardcovers. They aren't even all that unreasonably priced, especially in book club and/or combined/omnibus editions. But they're BULKY compared to paperbacks, and given limits on shelf space and space for shelves...
(Realistically, I'm likely to wind up with a house whose walls are insulated by a thick layer of books...)
