I have AEBN inside my members area. I charge my Members and tell them "Look, I am not rich, I am a poo mofo and can't afford to pay for the bandwidth.. bla bla bla.. . And I make a few hun per month on that.. They also offer upsells.. etc
http://www.aebn.com
I also have Camgirls Live which converts really really nice for me, however what works for me might not work for you. I have Amateur sites and both aebn and camgirls live have amateurs.
If you are into the fetish scene there are some really good upsell live feeds out there. like vampire vault and stuff..
amateurcamz is starting a ghoth live cam..
hope that helped a bit
