Solmeta Geotagger N2 - The ideal GPS receiver for Nikon dSLR cameras. Simply attach the device to your camera, all the photos taken are geotagged with precise location (longitude, latitude, altitude and heading) and UTC time information.
I own a D90 have just placed an order for this device to take on vacation. Best review I found on the device was by Michael Kirk on a Flickr Group.
