Hoping someone can give me some insights into which gps to buy. i'm really clueless as to what i need, and what is best. So which one would you buy: (these are roughly the same price and available to me now) New dakota 20 New etrex 20x Used gpsmap 62s (1 year of use) Used oregon 450 (used since 2010) Thanks a lot in advance!
