I am having the same dilemma as well!! I have narrowed mine down to the etrex 30. What I feel are pros to me were that the etrex can track glonass sats as well as gps (quicker and more accurate, but i assume they all will do this eventually). I can load topo maps to it and it has good battery life and small. cons its a smaller screen and if touch screen is important then the etrex is not for you. good luck on your search!!
