http://www.etology.com/buying-package-network-list.php?sid=569bbddecd718c9e45a512e94625e96f gives you an idea on cpc. looking at that, you'll get mostly 2 cents a click minus their cut.
i use etology. It's not bad, it's not amazing either. Then again, it is still in beta version, it basically gives you 75% of what advertisers pay and you can see what they pay on your reports. Might be better later on. I think my average CPC is 4 cents or so. It does the trick for now, but i'm always open to more suggestions.
