Good feedback. I run a garmin 550 and recently came across a 660 but am not that impressed with it. Maybe I just like the bike features of the 550 for trip statistics while rolling and such. What is your plan for bad weather? I was riding in the storm that came through the east coast last week and my dry gear leaked as well as my travel bag due to the volume of water. Of course I figure not looking at the gps in a mess like that but you get the point. I don't have the tough case on mine.
