I've only had a quick look at them so far. Love the feel of the covers. Font is a bit off but I'm pretty happy with them overall.
I have several copies of all three books that I have picked up over the years, so these were a want rather than a need. I believe at least two in my gaming group picked them up as well.
I bought these primarily to say to tell WotC to start supporting early editions and to help support the Gygax Memorial. It doesn't hurt to have an extra set of books for when I start teaching my kids to play either.
Did you get these books? What do you think?
