As much as I would like to not have this issue, I won't just pass this issue along to someone else. I'm confident I can get a good resolution to this issue.
There is no mantra with
any object that says, "Till death do we part."
People pass along their problems all the time ... lenses with fungus, scratches, dust, etc. ... and there is nothing wrong with this, so long as you disclose the issue.
Now, if you try to pass the camera as "perfect," then you may be in foul territory, but if you say, "has occasional card read trouble," and offer the item at a decent price, there is nothing wrong with doing this.
Go ready the eBay ads ... there are tons and tons and tons of photography items with flaws being sold every day. (Many people actually seek these out in order to get good deals.)
Again, you're not required to "own something till death" ... you can dump it any time you want.
But if you'd prefer to send it back to Nikon forever, and hope for the best, you can do that too
