Good old Dragon magazine. I still have a few sitting in a magazine rack. A treasure trove of great ideas, modules and such. All of the math/stats are for D&D 2nd Edition but that's hardly relevant to a DM just looking for interesting adventures and stories to tell.

Oooh yeah, Dragon! When magic didn't rely on small girl with wands, or teenage heartthrobs with sparkles. And they wern't afraid to mock their own craziness either. "You want me to sneak up on a dragon, over a landscape of heaps of metal coins?"
