Site Pass
-Spent some time researching AVS's and found these guys, they rock.
-You can create a site and it doesnt have to be approved, (although it wont be listed on their link lists) But you still get paid, and can do just about anything you like.
-They have always paid me on time, for nearly a year.
-Not many people heard of them so conversions are good, I've had 1:83 conversion from just under 10k hits to join pages. From a combo of SE and TGP traffic.
-When the user first signs up, they actually get directly into your site without being hijacked into confusing middle pages. So you actually get a shot at upselling them!
-ARS uses them for their inhouse AVS system, so apparently there is decent inhouse traffic, although I've never bothered to get approved, to test its quality.
