Geomet'r GPS Receiver for Nikon D200 D300 and Fujifilm S5 Pro DSLR CamerasIs a new GPS unit at a very competative price.
Easy to use and powered from the camera.
There is only one "but" as I see it, it doesn't have the 10 pin connector
so you can't use a release cord at the same time.
Sold by Amazon.com for 129 USD (20080425)
