A friend's wife wants to get him a GPS, looking at the $100 to $175 price range, like the Garmin etrek or Magellan Sportrak. She wants me to help find a good one for him. So, do I need "WAAS enabled", does it make a difference is accuracy? Will I be happy without WAAS? Does anyone have comments on the two units above, and was yours WAAS enabled? How accurate should I expect -- how many meters does it get you to your spot? Any other models we should look at, or which ones to stay away from? Thanks for any inputs.
