wow nice quick responses.
i think you've sold me on the oregon 450
etrex 20 list price = $199 (on sale for $170) 15% savings
oregon 450 list price = $330 (on sale for $199) 40% savings!
either would be an upgrade to my current gpsmap60 (original, 2001 model). the grip rubber is almost all worn off; the buttons lost their paint and i only know which button to press by memory, plus some buttons have broken in half and are interesting to press. but it served me well (over 1400 caches), and stood up to plenty of drops (including one in the river).
