So after three months of use, my NaviGPS GT-11 has stopped working shortly after Christmas. It seems the built-in battery is dead. I can't say I'm too happy with the product -- aside from the battery problem, GPS reception has also been less than convincing.

Even though it's too expensive, I'm considering getting a Garmin Etrex Vista HCx. Is it feasible to take an Etrex for a run?
