I have been thinking of buying myself a new gps also, and have decided on either the Etrex vista or Magellan sportrack pro. Both units have mapping abilities and a compass. They both have the same water proof standard. They also include more memory for mapping then their siblings. price range $250.00-350.00.
If the amount of memory for maps is less important then cost, you could go for the Etrex legend(blue) or the sporttrack map. Price range $185.00-250.00 They both offer maps and waterproof standard. But less memory meaning less map. I also believe that the Sporttrack includes a compass. As for the serial cable, I think that they all come with that and that usb is not a option. I would recommend a A-B switch though you have to make sure it is switched properly each time you boot the computer. Hope this helps
