Re: GPSMap 76???
You can't compare the 76 with the H2O, I mean, you just did. But is not apple to apple. The H2O is a better unit as it is a newer unit. I highly recomend Garmin. For one thing, their customer support is unsurpased. but I would recomend a newer unit like the 60 series.
Another thing, try to get you unit locally if you can and make sure you can return the GPS if not satisfied. I went thru 3 units, including the H2O before finding the unit I liked. Everything looks and sounds great on paper, until you try it. Good luck.
