I think I am going IPHONE on the cheap for now. I don't do alot of off trail stuff (though maybe would if I had an oregon unit). I really only want it to tell me lat/long info that I can correlate with my map to find my position because of snow cover on the MMWT. I'm heading out 6/26 and I'm certain there will be lots of snow cover and I'll need some route finding training wheels (i've always been bad at triangulating). Any thoughts on aps?
