I have a cam site and I purchased from everyone as a test in the years, from trafficshop / trafficholder to juicyads, ero-advertising, various tubes, just made an account at exoclick to test and so on. Actually those blind skim traffic convert bad even on cams but does clicked banner convert that better? And what about the cost and total availability?
I make one example: I have the cam plugin in member areas of several pay sites, these can convert 1:100 but how much total traffic they can send? Sure 1:100 is nice but if they send max 100 a day (then less after a while) that's 1 signup a day only, and have to deal with each site to put the link and this take lots of time as we know many webmasters are so late to reply or do things, it can take months for a link in a member area to happen.
Also I tried direct deals with medium big free sites like tgp and blogs and except few cases, I did not saved that many money or I've put the banner there and conversion sucked same as redirect blind stuff.
So it can be worth to consider also 1:10,000 conversion traffic if that can be started and stopped on same day via a control panel, after you pay it, if cost cheap enough, and you can get big amount like 20,000+ per hour that's 2 signups per hour, just an example.
The issue with direct deals is have not to icq and email many lazy webmasters who say hey bro blah blah but then never put your damn link before of spending the 6 months with 20 reminders - then you find out his site is so dead with little traffic, it was not even worth.
By the way Chocker I made an account at yours time ago then seen no one way I can pay you quickly (unless I give evidence I am not bin laden) so I gave up
