I got the di-GPS before a major trip (3 weeks) to Laos and Thailand, about maybe 5 or 6 months ago. Here are my notes:
Good points:
di-GPS got the unit to me faster than many orders coming from New York (I live in Az.)
The folks at the store in HK are great, they know the idea of "Custom Service", I had a problem with the order (it was me, not them) and they went way out of the way to fix the problem.
It is small, it fits on the camera just fine, the plug was a little hard to fit, but that may be just a good seal.
"It just works"
Same reading as my 60 CSx (but the camera has one less digit)
The remote works great, and much cheaper than Nikon
Very easy to use (Plug and play)
"Areas for improvement":
The packing was more for selling in a store, not shipping across the world
Time to first fix sometimes took a long time (it felt like 5 to 10 minutes!) and that
was with a clear view of the sky, other times less than a minute. I would turn
it on early but getting a fix in a Tuk-Tuk did not alway work well.
It sucks power from the camera, With my D200, I can get 12 hours or more with
one battery, with the di-GPS power is used power 3 times faster (Yes only about 4
hours per battery, good thing I got a third battery for the trip)
It does not "feel" as if it is the same build level as a D200, My unit worked fine with
"normal" use, but others have had problems with the unit not holding up to the
live of a D200.
If you need the flash, you have to pop the di-GPS out of the shoe, but it will still
work fine even if it is hanging loose.
I did not use it all the time, due to battery drain. I tried to use it for the first shoots at each Wat, but the time to fix was to long in many cased, so I started shooting before the fix.

I second the di-GPS. I just bought one a couple weeks ago. It's
awesome. Just turn it on and shoot. I was a little leary about
shipping time and such (coming from Hong Kong to US), but it took
almost exactly 36hrs (from placing order to the Fed-Ex guy knocking
on my door)! I was amazed.
Once it acquires signal (between 2 and 45 seconds or so, depending on
how long it's been since you last had it on), it seems to keep signal
very well. I can walk anywhere inside my house and it still works.
Some people might think you're a bit strange (or obsessed), but I
think you'll see GPS on every camera in the near future. Just my
outlook.
The bluetooth idea is kind of appealing, but don't really care to
have something else to worry about losing, running out of batteries,
carrying more chargers, yada, yada...
Enjoy!

navigation...)
