They recommended the Montana stating that the screen was easier to use with gloves on and less expensive. I guess I'm back to what is it that I really need - really just a good GPS that has trails on it. They also recommended that it be purchased with Topo maps and City Navigator..
They make a good point: The Montana is excellent to use with gloves.
I've got City Navigator and Birdseye. I don't like the topo maps because all the lines make it more difficult to see the marked trails. The City navigator map has shaded representations of elevation, which is enough for my needs.
