Borrow? Heck no! I outright steal. I take it home, file the serial numbers off, slap on a new coat of paint, and my players don't know the difference.
I generally take from works of fiction, rather than published game settings. Most of my players read lighter fiction. So, my penchant for epic fantasy means I have loads of source material my players have never seen.
