Have you looked at Magellan's new Triton Series?

It's the next generation (or so Magellan hopes) GPSr. They seem to have everything plus the kitchen sink.

The top of the line maps, has expandable memory, has a touch-screen, records sound, plays mp3s, has a built-in camera and an LED flashlight. Everything is supposedly integrated so I can record a memo and/or take a picture and it is all linked later to a waypoint or on your track. I've never actually held one and it's too new for info on the durability of all the bells and whistles, but it sure looks great.
