I run
http://www.Teen-Paradise.us/links, and for that matter 20 other niche sites.
However dunno if it fits anyones criteria here as it is a paysite, and I don't put recip links on the main index, but in the above designated links section.
I can however make a deal and put your recip in several of my paysites, if you put a link to me on your main index page.
Let me know if anyone is interested.
