Great guys for all the help, it appears the Etrex is the one to get. Now what's the difference between Etrex 20 and 30 besides cost?
Then I noticed Garmin has two types of maps, Topo US 100k and Garmin Street Maps and Navigation called the City Navigator NT, which of the two is best for road touring? or can both be inside the unit and accessed separately?
The etrex 30 adds a barometric altimeter, electronic compass and the ability to wirelessly transfer information. Other than that, the 20 and 30 are only different colors.
Open Street maps are free and can be downloaded for nearly any part of the planet. Here's a link
We've been using an older etrex for years with Open Street maps around the world. It recently was killed in a horrendous downpour in Turkey due to a well known (fixed in the 10/20/30 series) design flaw. We will be happily returning to touring in New Zealand and Australia in 6 weeks with our new etrex 30! We don't need it for turn by turn directions, only to verify general navigation decisions on the bike. Off the bike, we regularly take it into the backcountry, especially in the snowy winter where trails don't exist.
Enjoy the ride,
