I stumbled across this product the other day, and was wondering if anyone here had any experience with it.

It's basically a small GPS logger that you time-sync with your camera. When you get home, you download your pictures and the GPS data. It merges them, based on timestamps, creating a Google Earth file with your pictures linked to the location you took them at.

I'm a Google Earth nut, so will probably end up getting this if I don't hear any horror stories.
Found it at Amazon for $50.

Thanks,
Doug
