The Complete Book of Eldritch Might is invaluable; I would be hard-pressed to run a game without at least one copy at the table.

 

[MoogleEmpMog]

Conan the Roleplaying Game (technically OGL; it replaces the "core 3")
d20 Modern
OGL Steampunk (technically OGL)
Iron Kingdoms Character Guide
Complete Adventurer
Complete Arcane

I doubt I could run my current campaign without having those six books. I keep Arcana Unearthed handy for the exotic armors, too.
