We have a Garmin Nuvi, several years old and it has been fine. I have never used anything but this unit so I can't comment as to pros/cons compared to others. Just remember, no matter how great a gps is, they are not perfect. You have to also know where you are going especially if you don't update your maps. Before we updated this spring we would find ourselves confused (not hard to do) because the gps would not know the road was changed, added, or removed.
