Well, consider that you can easily find one success story for every failure, but more importantly consider that people with success generally don't go online to write something.
Nikon's reputation frankly is pretty bad right now, but I never even considered finding a 3rd party when I needed to send mine in. They broke it, they should fix it, and if they can't fix it why would I think someone outside of Nikon's inner circle could -- it's not like Nikon has a reputation for sharing engineering information with their 3rd party network.
I would hesitate sending one in that could be fine tuned to be acceptable, even if it wasn't perfect. But if it's focus is out of calibration, I view them as the only viable game in town.
Unless you can figure out how to get another country's team to fix it.
