I agree with Frank's evaluation of fx-260, except one thing: the older model fx-250D is even better for navigation. The main advantage is that it has sexagesimal input option. This feature they discontinued long ago. I even once had a conversation with Casio representative on some exhibition, and asked why. He said "Who needs that?"
But fx-250 needs a battery (which works for many years). I have both of them.
