The Nikon GP-1 is so expensive I wouldn't even consider it. I've been using ebay item 370260641559 with my D90 and it seems to work as expected. I needed to put a strip of tape under the foot to make it a bit firmer in the flash shoe but that's been the only problem. I believe there's a supplier in the USA that also sells it. Item 170388341342 is also a possibility and looks like a more polished product.
Whichever one you go for, I recommend using the KUSO EXIF viewer to look at the GPS data. It has the advantage that it'll drop the co-ordinates straight into maps.google.com.
My feeling is that you get what you pay for. I started out with an external pocket GPS they all work if you don't mind third party software to marry the GPS data to your images. And don't forget the extra time in post to add the GPS data. Or if you forget to sync the time between the external GPS and the D5000 the GPS locations won't lineup with your images.
After several months I then purchased the Nikon GP-1 it was well worth the money for the convenience of having the GPS data embedded into my pictures as they are taken.
My only complaint is the cable connecting the GP-1 to the D5000 is to long it could be half the length.

I'm not very familiar with the D5000. However, before Nikon introduced their GP-1, I successfully mounted a Geko 301 GPS unit to my D300, using the Nikon MC-35 GPS cord. I attached the Geko to the hotshoe using, of all things, a rubber cushion that fits between a toilet tank and bowl (don't laugh, it worked really well and it only took 2 minutes to find it on my workbench and cut it down to size!). The Geko 301 was at that time the smallest hand-held unit on the market, so it was very lightweight, plus I could use it off-camera for hiking. The MC-35 cord was quite long and bulky, so I attached the extra cable to the bottom of my camera using velcro for a strong but easy on/off attachment. The only watchout is that you'll need to cover your serial number so that the tape from the velcro doesn't lift off the serial number if you ever decide to take the velcro off.
This rig worked well, and all of the GPS data was automatically logged into the exif file. I didn't have to do anything at all for the info to show up in the exif data. If you want the coordinates to be translated into a city or town alpha name, there are plenty of programs that will do that for you (if you post online, Flickr does it automatically when it reads the coordinates from the exif data).
It's not quite as sleek as the GP-1, but it does the job and the GPS can be removed and used conventionally. BTW, the MC-35 cord allows the use of a flash in the hotshoe while the GPS is connected. In that scenario, you can mount the GPS on a straight flash bracket ($10), or you can just let the GPS dangle while the flash is in the hot shoe. Or if the D5000 permits (?), you might be able to keep the GPS in the hot shoe and fire your flash off-camera in Wireless Commander mode.
Like the D90 the D5000 uses the MC-DC2 remote release and the port that this corded remote plugs into not only supports the shutter release but also has a data port like the D90 and like the D90 does not have the 10 pin accessory port. So you use the same cord, GP1-CA90, that the D90 uses. This cord is supplied with the GP-1.
See page 114 of your D5000 manual for instructions on how to attach the GP-1 GPS unit.
I would consider a GPS that can log position and then add the GPS as a post processing step. This will allow for shooting with multiple cameras or geotagging images for a group. Depending upon what GPS you get, you may have a GPS that can be used for directions, hiking and geocaching. There are handheld models for 1/2 the price of the Nikon unit.
Solmeta GPS units are sold by the Nikonians shop. They have a few advantages over the Nikon GP-1, like recording orientation and (iirc) being able to run from their own battery and not drain the camera. But the price is up there with the GP-1.
I am using a brand new Easytagger gps which you may find it here at www.e-geotag.com
It can geotag in real time, when you take the photo, the gps information is already in the EXIF and it also has a 2Gb micro SD card to store at least 3 years way points. With that, it can allow one to geotag images from any other digital cameras.
It also has the features below
Barometric altimeter integrated
Built-in 2 axis magnetic sensor to show direction
Auto geotag indoors by memorise the last received GPS signal when losing satellites
That is your opinion. Realtors can use the GPS data to mark and link to locations on map. Researchers can establish the location of the photographer when taking images of natural features, plants, etc and return the the same location to take a comparison shot or relocate the location. Hikers can use GPS to document their location on trails. Travelers can use it to map their travels.
Non-photographic use, notify emergency personnel of your location when off the hard surface road and you run into trouble, like a trial on Mount Washington in January. The GPS is use with my camrea can even aid in providing driving directions, so I do not need to buy a $1,000.00 builtin GPS unit for my car or I can add a GPS unit to a car that does not have one.
