Eyetracking User Interfaces

Mike Rundle tells me that he has posted about Attentional Spotlighting in User Interfaces to the Business Logs blog. The post covers some interesting theories about eyetracking usability tests. He makes some very good points here, however there is one part I disagree with. I believe that eyetracking tests should only be done with a "potential user" and not with someone who is already a user and familiar with the user interface. That aside, it's a great read and offers up some things that we should all be thinking about.
Nick, why would you only test with potential users?
Well, as the article points out, existing users have already established a familiarity with the site or system and therefore they already know what to expect. I suppose you'd test existing users if it was a redesign (e.g. a tweak here or there). My testing for Digital Web Magazine revealed that existing users experienced more of a design shock, while potential users really liked how the architecture innovative worked. Once it launched existing users slowly adopted the architecture and learned how easy it is to use. See this old post for some more insight here. Its one thing to evaluate something against a pre-existing or known system, but it's a whole different thing to actually put a new system to use in practical terms and evaluate its performance against itself.
I'd ask about methodology. DO U know some resourse where can I find some existing and working methodology base on psychology. I'm starting with eyetracking and I'm looking for the best company who offer me equipment and software.
