Query: Exactly what I wanted

It was tough choosing -- but I opted for the "cheapest" of the 600 series. Realistically, I don't care about Bluetooth, traffic, FM transmitter, carrying case, etc. I just wanted a good, no frills GPS -- and it's great at that job -- big screen, bright, normally very accurate -- and addressed most of the issues that I had with the earlier 320/330 Street Pilot series (which were no slouches). I used the money that I saved (and ocassionally Amazon does have this unit on sale) to buy the bean bag mount -- which is also excellent -- doesn't block view through windshield -- easy to remove from the car, etc. As far as I'm concerned, Garmin couldn't do much better value-wise than the 650 + bean bag mount.
