TrafficCashGold has tons for their two ebony sites Pimp my black Teen & Tiny Blacks
Pimproll has about 4 or 5 black sites with an absolute tone of galleries for each.
AdultDateLink has a few good ones for their black dating site. Good conversions cos not many in this niche are pushing them.
Oh, and see the sig.. I have been pushing them a bit recently and their site Ghetto Gaggers converts great. I actually thought it was too extreme for my surfers but I was wrong.
