Zanox, Adfish, Affiliatetraction... But I am sure there are lots of others as well. The question is to choose the best ones for a long-term cooperation.
Clickbooth is a great reputable company with A LOT of offers.
Copeac scores major points for being a smaller company that gets offer you want to run and makes an effort to pay higher than the others...And gives wires if you do 5k every ttwo weeks.
