What's the best way to find all the porn by a pornstar?

[Harry Tipper]

Until there exists a unified iTunes of porn, you have to search many different sites to find videos of each pornstar you want. It'd be great if there was one place to buy/download all the videos containing said performer. So far I've found the best way is to search
Premium Link Upgrade and Premium Link Upgrade
then join all the sites they span (which could range up to thousands of dollars) or endlessly search t0rrent sites (which provide variable quality and availability)
