I already had one 64GB N9 where I changed casing year ago from black to white due to peeling issues. However, I just bought one used, but good condition original black 64GB N9 for 103 EUR / 141 USD and I am quite happy with that deal.

*I have to admit that actually black casing looks a lot better on N9 than the white one. I just do not like the polycarbonate casings peeling issues...
