I have used a Garmin ETrex Vista CX for the last 3 or so years....I love it....When I am hunting or bowfishing I put in the Topo mini SD card.......when I am traveling to get to where I need to be or even on vacation I put in the road atlas mini SD card.

The only thing I can suggest is....whatever model you go with get one with a color screen you will not be dissapointed...I know I am not.
