My best is
MovieDollars. Their galleries convert better than AEBN, Xonair, etc, because the sample movies in the galleries are high quality. Also, they pay on time and have never bounced a check on me unlike AEBN. I also like their stats area and their selection of movies. Movie Dollars has a great selection niche stuff, like 'sissyfication', etc.
