Another option is the Garmin eTrex 10:

Full-blown GPS...waterproof.....GPS/Glonass for that extra bit of accuracy......track plotting, including TracBack, which guides you back to your start point the same way you came....none of those pesky mountains or swamps to worry about on your way back
Seem to be currently available just about anywhere at the moment...Johny Appleseed's got them for $145....Anaconda's got them for $127.20.
I've used one for years now for back-country trout fishing....always switched on when I'm out, and never flattened the batteries in a day yet.
Handbook here for anyone interested:
