I agree with fris......I do buy traffic but its only through contextual ads which are solely text so it qualifies the traffic before they even click. You'll get more clicks through images and stuff but once they see that they are not interested in what you're offering, they move on. Reading the text before they click usually means you get viewers that are already interested in what you're offering by the time they click through.
I send direct to sponsor and to my own landing pages this way.
You can check my sig if you want targeted clicks for a very reasonable price.
(btw, for those thinking about trademark TOS violations concerning search marketing, the sponsor I send so far doesn't have that provision yet in their TOS which I check on a regular basis)
