Any of you guys have suggestions for a good handheld Topo device? I understand most are GPS with Topo option. Just wondering what you thought about what's out there..

I have a Garmin 60CS and really like it. I think the newer model has the ability to use mini-sd cards so you can download different areas and use which ever one you need. But I really don't see the advantage since mine has a big enough memory to download nearly the whole state.
