I could recommend several 3.0 modules, but since they aren't by WOTC/Paizo they utilize a generic setting/open license gods for adventure back grounds. Also, it would probably prove difficult for you to get them, unless you buy pdf.
My favorite is Wizards Amulet/Crucible of Freya. I like it mostly because of the free downloads available at Necromancers website that gives a whole bunch of additional encounter/locations to the environs around which the Crucible of Freya is based (Fairhill).
Crucible itself is a fairly basic adventure, but solid with lots of potential to go in any direction a DM wants. Some will also cry about how deadly the module is, and they are right, but any DM who knows how to DM can easily modify the adventures to be less deadly.
I also like a number of other adventures by Kenzer Co., Penumbra, Goodman Games, Troll Lord Games, Fiery Dragon (NeMoren's Vault), and Ed Cha (he plugged himself earlier in this thread, BTW Ed, congrats on the ENNIE nomination). Dungeon is also worth checking out, especially since they often use Greyhawk/FR as module backgrounds.
Another excellent, but very expensive ($35 full retail) is Lost City of Barakus. It is a well fleshed out city (Endhome) and dungeon crawl (The Lost City of Barakus), that has a number of adventure outlines for a DM to flesh out. IT is meant for levels 1 to 5, but can easily go beyond that. In fact I didn't start using it until 5th level and have easily scaled the adventures to be appropriately challenging.
