New but Credible PPC

Usually when people ask about place to run PPC campaigns the usually suspects come up (yahoo, Google, MSN, Chitika, Clicksor, Adbrite and Bidvertiser). I just wanted to know of any other good companies out there to run ppc campaigns on. I heard that their are some vertical specific ones that are good some that deal with just travel some that just do gay ads. Let me know if you guys know of any other? Thanks
