Choker has his share of jealous bitchass haters...his traffic is fucking good...
there are only two polaces I regularly buy traffic:
www.chokertraffic.com and
www.askjolene.com both give a solid ROI. Choker has good feeder and gallery traffic, askjolene has amazing gallery traffic but can be a little slower on delivery depending upon niche, but it's higher quality traffic (you can stick a recip to them and your TGP on the galleries you list with them and it'll trickle some decent traffic into your TGP as well
Be sure to start smaller and tweak and test their traffic with different niches. For just regular feeder traffic, Choker's freesite traffic is decent but you'll want to make sure to filter your traffic a bit more.
