I would respectfully differ. I think that unless the market for all comics slackens considerably that the base price for the Big 2 (action 1, tec 27) will be 100K for anything complete and at all presentable. I think the buyers for this and the comiclink copy both got pretty good deals considering the longterm, and while there may be other deals for this and tec 27 that come along, a buyer can't count on copies appearing the way they can for lesser books.
How long can a book with PCB pages last? I used to not care about PQ, but after holding a few books and unintentionally flaking pieces off just by turning the pages, this book could fall apart in the holder. Not likely, but possible.
