Hello all. I have a line on two used GPSes: Oregon 300 and Montana 650. The Montana is a lot more money, but comes with some mounts and extra maps. I really have no need for the camera on the GPS. The Oregon is probably capable of fulfilling my needs, but maybe is getting a little older. Apparently the screen is difficult to see. Can somebody help explain to me (or help me justify) why I should spend 4 times the money on a Montana over an Oregon. Montana ~ $400 Oregon ~$100 My uses are going to be mostly on-road motorcycling, with some back-road and off-road interspersed. Also, it would be nice to be able to use the unit in my car when I am not riding. (Trying to save money on the cell phone plan by reducing data usage). Thanks in advance. Trying to make a decision soon, so your help is appreciated.
