Etrex Vista CX
Caru,
I've had the Vista since August or so and have really enjoyed it both on the bike(s), and in the car and motorcycle.
On the bikes we use it for tracking the routes and the usual navigation in the car or motorcycle. It's small enough to fit on the handlebars but functional as the bigger units in the car.
The display is great in the sun and the battery life is phenomenal (20-30 hours). I use rechargable NiMhs and have found to ALWAYS replace before a ride.
You can then load the track back to the pc and see the profile, map it, or other features like gpsvisualizer.com and Goggle Earth. It's fun to 'fly' over your latest century with Google Earth.
