Try Adult Traders:

(I get 12% for any traffic you buy if you sign up using my referral code ;)
They've worked very well for my TGP, Evil Purple (
http://www.evilpurple.com), or I wouldn't have cared about getting the referral traffic :-)
It's clicked, and has quite good productivity. The users are coming from various Enter links etc. on TGP galleries.
