GPS for the D7000

I have done some research into the GPS unit for the D7000.  Apparently, the D7000 shares the same GPS connection plug as the D90 so I suppose I could buy a GPS unit for the D7000 and it will work on the D90 as well.  Sweet.

First though, I do not want to purchase the Nikon GP-1.  It is very expensive considering its limited functionality.  There are a number of third-party units:

Yongnuo N-918/N3 ($65)
Columbus nGPS ($90)
Phottix GPS Geo One ($160)
JYC N-769/N3 ($125)
Solmeta GPS N1 ($111)
Solmeta GPS Pro ($250)
PC-Mobile ($80)
Opteka GPN-1 ($85)

Now, I cannot buy the Yongnuo GPS unit yet.  The GPS port of the D7000, while the same as the D90, is reversed from the D90.  There is a notch on the D90 that points toward the front of the camera, while the notch on the D7000 points toward the back of the camera.  The Yongnuo GPS units were designed with an L-shape plug for the D90 so they fit well.  With the D7000, the cable may not be long enough because of the orientation of the plug, and because of the orientation, the cable points downwards and can cause the GPS port to break if not handled with care.

The Columbus nGPS could work.  It comes with a connection plug that is straight, but then, the cable would stick out too much and it would be easy to break the GPS port as well.

The JYC unit looks very similar to the Yongnuo.  Why the price difference, I wonder?  The only difference I can see is the connection plug.  The JYC has a straight plug vs. the L-shape plug of the Yongnuo.

The PC-Mobile GPS unit might work.  It has a connection plug that is modular.  It can be oriented up or down, depending on whether you use a D90 or a D7000.

The Phottix GPS unit looks very similar to the Nikon GP-1.  I have no idea whether the Phottix GPS unit will work though.  Again, it is a connection plug issue.  There are no images of the plug that I can find.

The Solmeta GPS N1 unit has a rechargeable battery.  Cool.  It has can come with a cable for either the D90 or the D7000.  You have to order one of the other.  I guess you could ask for two cables for an additional charges.

The Solmeta GPS  Pro unit is probably the best of the bunch in terms of functionality.  It even has an LCD display at the back that displays the current coordinates, date, time, and memory.  It has a rechargeable battery that can last for twenty hours--a real plus--so it does not draw power from the camera until the rechargeable battery is depleted!  As with the N1 version, it comes with one of a variety of cables.  You choose one.  The price is too high though.

The Opteka GPN-1 unit is claimed to work with the D7000 so it should work with the D90 as well.  However, I cannot find any image of the connection plug.

I am leaning toward getting the PC-Mobile GPS unit.  It is a simple device that can work with both the D90 and the D7000.
