I don't necessarily need one with all the bells and whistles. I'd like something where I can set a "home" area, take off walking, and have it guide me back when I'm ready to return. I've looked at the Bushnell backtrack's and they get mixed reviews. If it takes buying a more expensive model in order to get quality, so be it. I don't really need all the topographic maps and such that come on them though. Suggestions???
