Garmin GPSMAP 62s

i am looking to pick up a new GPS for my elk/deer hunts this winter, i am almost sure i want to get a garminGPSMAP62s, and i want to get a NM card from huntingmaps.com, i was wondering if this GPS is over kill and if could get away with A less expensive one, or what everyone out there had to say about this, thanks

etrex 20 is a good gps for about half the price of a gpsmap 62s. you can get them on amazon for about $180. i got one and it works great, the only thing i dont like is the screen is kind of small.
