I live just down the street from KORF. When I saw the Cavusim Norfolk package last week I compared the screenshots to the actual airport as viewed on Google Earth. I thought they did a pretty good job of including all the major facilities. As for the lack of structure detail in the passenger terminal area, frankly there's not that much there to begin with; the terminal wings are rather nondescript brown structures. On the plus side the GA ramp by Landmark Aviation and the cargo area appear accurately reproduced, also the tower and FAA building and the fire station. Try the freeware offering in the files here first, as I am going to do. If it works for you, great, if not the Cavusim package is a good deal for the price with way more detail than the default KORF which I just reconned before I posted this.
