The softcover printed version is really nice, good square binding, glossy color cover, good interior color.
My only gripe is that it is a thick book, and the pages are printed too far into the crack in the middle of the binding. To read it comfortably, I will eventually crack and crease the nice square binding. It's a small quibble, and one many people will overlook, but some of us Book People are a little crazy.
It looks like the printing could be shifted 1/8 of an inch toward the outer edge without too much crowding. This isn't a lot, but it could help.
Otherwise, it is well made, and worth the purchase.
I give it a 4.5 / 5, rounded up because checkboxes.
And cut-and-pasting from a review from Brent C. "My only hope is that other box sets will recieve print-on-demand hardcover versions (coughPlanescapecough)" I can't say that loud enough.
