What do you guys promote via PPC?

I used to promote CB products via PPC but it did not end up yielding any high profits. I am a n00b so I do not have access to many CPA Networks. I had started a thread a couple of weeks ago enquiring about networks which accept PPC traffic but did not get any useful reply. So, once again I would wish to know which networks can I apply to or if someone here has his own product and needs some PPC promotion, hit me up.
