Yikes! For $175, it would have to come with fold-out battlemaps for all the encounters too for it to be worth paying the price. I already bought the whole saga on PDF and it really isn't that expensive for me to print it out myself if I were to do it in B&W. Heck, I could do the whole thing in full color on my own printer for that price, possibly lower.
I realize Paizo is a larger publishing entity and thus can defray the expenses of a print run more easily than EN Publishing, but their AP only cost $60 for a full-color hardback and it sounds like about the same amount of material for 1/3 the price. I would find it hard to justify spending this much on an AP hardback unless I were swimming in money, which I am not. Not that the WotBS is not a cool campaign. I just find the hardback price tag a bit cost-prohibitive for the public at-large.
