For what it's worth. I'm kinda in the same boat you are. I just bought my Colorado 400c in May. It's already puked on me (would not power up) . I returned it to Garmin for repair and the repaired unit should be here tomorrow. I was looking for an updated status and saw the Oregon suddenly appear. I was a little miffed that I could have had a touch screen. But now that I've done a little reading and thinking, a touch screen may not be the cat's meow if it's raining, muddy or cold.
And based on all the Software issues with the Colorado........just wait and see what happens with the Oregon. (Unless they put the 'A' team on Oregon and 'B' team on Colorado). I'd wait a year and see what kind of updates and serious user reviews come out on Oregon.
