I cast another vote for the Garmin 62 series, and NOT Delorme, etrex, and absolutely not a cellphone. Reasons I like the 62? a) strong reception even in canyons and some overstory - the antenna is unmatched, b) buttons (just say NO to touchscreen for GPS, c) very water resistant (at least mine is). The 62 series models vary only slightly in features, mainly the preloaded/downloaded maps that go with it and some other things (compass; camera); I got mine because it was on sale at REI, a year ago, and was again last week - not sure about this moment. There are lots of free digital maps (topos, streets, etc.) available that you can load into memory cards besides the pay versions that Garmin (and other vendors) sell, and they work fine, with less bells and whistles than the pay versions. I played around with the loading of aerial photo/satellite imagery, and haven't got much use from it due to the resolution. I wouldn't want a larger screen than what Garmin has now. Also, I've had good technical support from Garmin on learning the functions, and the BaseCamp program that Garmin provides for computer interfacing is convenient for looking at things on big screens and typing on keyboards if you are into that. The digital compass/altimeter feature is nice, but it does have to be regularly calibrated. I use the longer-lasting lithium batteries, and keep the unit on pretty much all the time when I am moving.
