I currently own older etrex and would like to upgrade to something newer and better. I have narrowed down my search to the Dakota and the Oregon. I like the Oregon because some models come with topo maps preloaded(my local sporting goods store is selling the dakota in a bundle pack that comes with downloads for several topo maps) however, I like the Dakota because of the price and it's screen seems to be more visible in direct sunlight. I have also heard that the Oregon views it's topo maps in 3D, is this any better than the standard topo maps? Which would you recommend?
