Looking for “New” 3DS LL and “New” 2DS LL

I am traveling to Japan in December and wanted to try and look a used "New" 2ds or 3ds. From what I have been seeing and hearing is looking within book-offs. Would Nagoya be a good city to look that would have reasonable prices? I would also assume that the further I get from the center for Nagoya the prices might also be less as well?

Also what are the current prices looking like within Japan compared to America?
