For a change of pace, while still being D&D, I'd seriously consider a campaign module like
*An adventure path from Dungeon (Levels 1 - 20 or customize to end where you want it to)
*Red Hand of Doom or the upcoming Expedition to Castle Ravenloft (5 or 6 levels only, so it takes less time to finish)
If you are after a setting, a lot of good ones have been recommended.
If you want a big change in flavor your might go for something like Hamunaptra or Testament from Green Ronin
If you like to build your own, then rather than buy a setting, I'd consider one of the genre series from Wizards of the Coast - probably Heroes of Battle for a War Game, but maybe Heroes of Horror if your group would go for it. Red Hand of Doom and Expedition to Castle Ravenloft seem to almost be the pre-packaged versions of the adveture themes these two products suggest. Home grown vs off the shelf, as it were.
