really ORIGINAL solo girl sites
ringtones
work from home
instructional
amateur/home made (must really look like it was put together for "fun" and not be a corporate looking amateur site. It won't convert as well)

hit or miss:
teen sites
celeb sites
cam sites

I haven't done a lot of "typical" niche mailers like anal, tranny, bbw, etc. so don't have a lot of data on them on how well they'll do.
