horrorsex kickas ass...$14 per month per join actually ;)
plus they convert really well, so still a nice per click total....
and of course DarkDollars sites...we're going to be testing no trial options in the next few weeks...we'er thinking of just scrapping trials altogether...
www.sicpics.com doesn't convert as well as I'd hoped, but might spark some interest from your horror/gore traffic......
as for creating your own...go for it...I've always said "if you can't find a site for your niche, build a site for your niche" and be sure to let me know if you do and we'll toss you a little traffic ;)
