User Review: Garmin Colorado 300

The Rock'n'Roller wheel is just another gadget that will likely break or something. The fact you can only display one route at a time is horrible in on itself especially for this price. It also eats through batteries.

This GPS seems geared towards geocachers, so if you are using it for that, enjoy.

As for hikers and the sorts I don't recommend. Unless you download the beta firmware update you cannot reposition waypoints such as the 60CSx can.

I would suggest the 60CSx for hikers. It's cheaper.
