I liked the old 3x version that I picked up in my "reading but not playing days" and the S&W version has that beat hands down. The Lost City of Barakusis more than just a mega dungeon - there is enough of a setting presented to play this as a sandbox with multiple points of interest.
I am sorely tempted to run this after my summer hiatus away from DMing for the regular group.
It's 40 bucks over at the Frog God web store, and that really is a bargain - especially as the HC includes the PDF for instant gratification ;)
