Just been going through some competitor sites to see where they get their links from, and many seem to rely on Netster, which appears to be a pay per click engine.
Also noticed that when I was working though a list of directories posted somewhere on here, a lot of them had expired and they redirected me to Netster.

Netster pulls their PPC's mainly from Google and findnothing. So, theoretically, you can become listed on that site via one of the two services listed above.
