I picked up an ST60 a few days ago and it's a great TV. However, it's in my living room in my apartment and I often watch stuff during the day. I'm finding out now that the F8500 gets brighter and has an anti-reflective coating for better bright room performance. How much of a difference is there? I'm contemplating whether it's worth boxing this ST60 up and taking it back to Best Buy to get an F8500. There's also the 900 premium for the 50" versions, but that's ok with me if the performance difference is noticeable.
