Yahoo + Google = Money for Me. Where Else Can I go?

I am a good marketer with both adwords and google PPC.
I’d like to continue paying for traffic.
IT actually gets me MORE sales than my #1 rankings for many terms.
Are there any other ways I can pay for clicks ? I also use MSN but it isn’t as great.
What about banner ads? Are there any good banner networks that could lead me to equivalent ROI’s?
