Just to follow up on this - I just got my replacement DX. If it's a refurb, I can't tell - looks new to me.
It took a while to get here because Amazon sent it to my father's house in Houston, then he had to send to me here in Japan. Wasn't too bad.
My only concern was they included a new USB/wall charger. I was told to remove all accessories, so I shipped my old DX bare. Now I have 2 chargers. No big deal, even if they charged me for the second charger I'd consider it OK.
