Hi, newbie here. I am looking to buy my first GPS and take up geocaching. I can't afford the newer garmin's that are similar. I see on ebay the GPSMAP 60C is in the $170.00 range. At first I wanted to stay below $150.00 . But I was wondering about this item. It looks durable with a good screen. I know it has internal 56mb with no card avail. is this a major problem for a beginer? Should I look at another GPS like etrex for the same or less money? I realize this has already been discussed many times in this forum, but I don't see this exact model being discussed. Thanks for any input, and Happy Valentines Day!
