Secondary Pay Per Click Search Engines Official List

Looking to create an official list of all the secondary search engines and networks that you can buy PPC from.
I will start with a couple. Then….if someone can rank them their favorites first that would help everyone.
Abrite.com
clicksor.com
7search.com
bidvertiser.com
chitika.com
peakclick.com
What else are we missing?
