The garmin etrex series are really good. I currently have a garmin etrex legend. It gets the job done. Looking to upgrade though.
I am also in Iraq, on the VBC, my etrex legend comes with carrying case, all software, manuals, and cables. originally 200 dollars, looking to sell for 100.
Send me an email to armyaviation83@hotmail.com if you are interested. I am on Striker.
