Well I should have prefaced my post by saying that my dear wife knew I was thinking about getting a GPS and gave me $200 worth of Amazon gift cards for our Anniversary. So I am somewhat limiting my purchase options for what I can get on Amazon. Finding the older discontinued models is a harder task. So I am basically looking at current or fairly recent models that can be found on Amazon. I just wanted to get a sense of other's experience on whether I would really be justified in adding another $600 to buy Zumo 595 for example. I appreciate all the input.
