I do. I've had it since GenCon, actually, and I think it's great.
For the reader in me, it provides month's worth of excellent DM fodder and entertainment.
For the little boy in me, it provides the friggin' biggest boxed set for 3.5, and fills it to the BRIM with books, handouts, setting stuff, maps and goodies like that.
For the DM in me, when I get to running it, I have little doubts it will easily be worth the price tag, for the sheer months and months (maybe year) of good gameplay.
