For Sale: diGPS Unit for Nikon D90/D5000

[PhotoXopher]

Geotag your photos the moment the shutter release is pressed with this GPS unit for the Nikon D90 and D5000.

$150 shipped, perfect condition - plug and play. Mounts on hot shoe or camera strap with the adapter (included).

Will consider reasonable offers, but I've got $180 into this and it's hardly been used at all.

How does it work? (not the technology, I mean your rating of this particular 3rd party GPS).
