I just saw on digg that javoedge (another company that makes PDA screen protectors) just launched some TSX and TL screen protectors. I was looking for the exact same thing the original poster was looking for. Thought I'd share what I've found.

Maybe you can contact them to see if they will make one for the highlander?
