It may well be a mistake to think "ill never use 2/3 of the features". If you get a device that can do many things well, you may find many of those things are useful in ways you didn't anticipate. One of the most important parts of making a GPS really useful, is to be able to connect with your computer and use it to manipulate waypoints, tracks, and routes, to improve their "usefulness" to you in many ways. I would advise sticking to brands and types that have lots of map options, software choices, and computer OS compatibility. As you grow into what the devices can do, you will find yourself using and enjoying them more than you anticipate in the beginning.
There is a reason the military developed the whole thing. They are very helpful if you ever get very far from roads and vehicles, especially in territory you don't know well. If you never get more than half a kilometer from your truck, you likely won't use much of the system's potential. If you really do hunt on foot, or actually travel in wilderness, they are marvelously helpful.
