I need to purchase a Garmin GPS bike computer for this trip to Holland. They have numerous models of Garmins to use but most of them do not have a long lasting ithilum battery. I will need one that will last at least 12 hours per day and easy to re-charge. Any suggestions? E Trex and Edge models if possible. Has anyone traveled to Europe with a GPS? if so, have you had any problems with Garmins or charging them?

Thanks a million.
