colorado 300
i have personally had the chance to try the colorado 300,400t oregon 300, and 400t...
while if you have any experience using a GPS you can understand why someone would opt for the colorado over the 60 series or the etrex series.... the colorado series has a great batter life and is easy to use with gloves on.. and extremely durable.
personally i felt that the Oregon series is even easier to use and has a better layout.
not sure exactly what your looking for but if you have more specific questions let me know!!!
