Anyone have any of the sets?

I'm (not so very seriously) considering getting the Everyman's 100 set (http://www.randomhouse.com/knopf/classics/sets.php?id=0). I have quite a few of the works bought individually, and was looking into buying the set in the same way - just buy the missing ones one at a time.

I was wondering if the set has a different style, or quality or something, to the "non-set" books. I've noticed paper thickness differences in various editions I have, and my anal-retentiveness would hate to have a mixture.

It would be nice of course to have the lot, but I have several of these already including Ulysses by Joyce, possibly the most excruciating read ever.
