I see Garmin Oregon 650T on sale at $399.99, I currently use and Oregon 450T which is working OK for me. I like the 650's brighter screen, huge cache capacity, camera, and other features. How ever read reviews of constant crashing, inaccuracy, and other problems. Those who have went from Oregon 450 to 600 series are you satisfied? Should I wait for more of the problems to be ironed out? Or would you pass on any of the Oregon 600's?
