I would definitely recommend the toolbar install (it pays $0.15) through an exit popup of
Gamma , it works with any straight/gay/tranny niche, and I have 1:15 conversions of surfers clicking Yes from the total number seeing the popup.
Also the mailers of
Freepassbucks and
CECash , or hosted photo or movie galleries of
Adult Platinum - $40/trial could work with good results.
