Etrex X 2
I have had an Etrex Legend for sometime that has served me well and is in your price range. Great for position fixes, will let you set up routes and do tracking, decent memory, and actually does mapping, although the screen is a bit small. That one I use in the cockpit and to verify fixes on the paper chart every hour. Will look to tie it into my autopilot and laptop this spring.Last year, my wife found a basic Etrex on sale at Aldi (a grocery store of all places) for about $70. I had her buy it as a back up. As Rick pointed out, having one hooked to the VHF for DSC distress adds some peace of mind, so that one sits at the nav station. Reception below decks is just fine.T J
