I bought the print version, and I'm very, very happy with how it turned out. The quality of the print is as good as my Ravenloft Campaign Setting original set, I can't tell the difference between the inside pictures on either of them. Print is very clear and readable.
Having everything in one big book is kind of nice, too. I'm pleased at how easy it is to have everything right where you could want it.
There are only two downsides. Number 1, is that I would always prefer to buy these items in hardcover. Whenever possible, I try to get hardcover versions. Softcover is alright, but there is nothing that can replace hardcover.
The second is that the maps are very tiny in the back. They are readable, but they aren't anything like what you get in the real set. It would be incredible if it could be done to get the maps as fold outs, or purchaseable separately as full size maps.
Other than that, wonderful purchase. I high reccommend getting these print on demand versions.
