The Etrex is a great GPS, still have mine from 2003 it's still perfect and in many ways better than my Foretrex 401. Love the fact that it has a serial port, makes it easy to interface with PIC microcontrollers and that sort of thing. It would be sad to see that thing go. I suppose they could improve on it a bit, but change it too much and they might make a mess of it
also hope they never discontinue the watch format GPS like the 401.
