I have project professional from GRN as well.. I really like it. Best of all they are a good company. I originally bought it for my 5500, and once I got my 760 I wanted to have it work on the nice big display, so I emailed them asking if they were going to update it, and they modified the app right away and emailed me the new version. I was surprised with how responsive and great they were.
It\'s on the pricey side, but I think it\'s worth paying for good quality software and support.
