Celebhotel from silvercash is supposed to be very good. I only have made one sale so far, but have only sent a tiny amount of traffic.
I have made my most sales with clebrityslutsexposed. It is from bizzare entertainment (sp?). I don't think they are very well known, but they pay through iBill and I have been happy with them.
Everyone and their mother sells CEN sites like Secret Celeb - so they can't be too bad.
I have made a couple sales from scoopy (cybererotica) and bad stars (conversioncash).
If I had to pick one - I would go with celebrityslutsexposed. It is partnership only. If I had to pick a per signup I think I would pick celeb hotel.
Just my 2 cents - I don't do a real good job promoting the celebrity sites - so I don't have a lot of data yet.
