i have a lower end garmin as well, its not the shiny color watch movies and listen to music kind of gps, just the basic black and white tell me were i am and were i been kinda thing. i think i gave like 110 bucks for it at bass pro a few years back, and it works great. but make sure you check your batteries before you go out, and deffinately play with it before you need it so you know how everything works. im a little over cautious though, i put up a little piece of contractors tape every 30 or so feet on a limb so i know i wont get lost, and when scouting if i find a good spot ill just leave them up so that i know im goin to were i want to.
