Though it was an early one, I really like Spear of the Loghin. A lot of original encounters, not too hard except for the climax, and very atmospheric. Unfortunately the 'sequels' are less good : BLood Reign of Nishanpur should have been double the size of the module and is quite heavy handed in its railroading, and Bloody Sands of Sicaris makes the PCs spectators to games of empire - active spectators to be sure, but still they aren't the focus of the story.
I also really like the Serpent Amphora trilogy, especially part one. A great mix of action and storytelling, in general.
