All of my GPSs have been Garmin and therefore I stayed with them and got the dezl 760. I've only used it in the truck so far, but I like it. The screens are a laid out a little better than my older Garmins and I like the large format.
While there's always some to stay away from (cheap off brands like cheap tires), of the top three brands, it's just like tires, trucks, cars, MHs, etc, it comes down to which one you like. Which ever one you buy, if you get it from Amazon and there's something you really don't like about it, sent it back and order a different one.
