This has been debated thoroughly, and although I've heard good arguments for bought content, I must say I make the most sales with sponsors with exclusive content and to sell them using generic-looking, bought content just doesn't fly.

One sponsor I can think of with tons of decent quality content is ATK Cash, and conversion ratio would vary on your traffic, although they're overpromoted and their stuff is not all over the place but isn't exclusive either. It usually takes about an hour or two to download their new stuff every month.
