Originally, I was aiming for the OG 3DS XL but the prices I saw were way higher than expected based on what I’d seen online. During the first half of my trip in Osaka, I checked out multiple Hard-Off and Hobby-Off stores. The XL models were going for around ¥41,000 ($260 USD) which felt pretty overpriced to me (tho I couldn't tell if overall market prices had spiked or if I was just hitting tourist trap shops). The selection in Kyoto wasn't any better, so I decided to hold off.
Things completely changed during the second half of my trip in Tokyo when I visited a Hard-Off in a local mall in Kamakura (Ofuna Mall). I was in absolute heaven. It was literally in the middle of nowhere with no tourists and only locals. Nobody spoke English but Google Translate did its job.
The prices here were much better than anything I saw in Akihabara or Osaka. Original 3DS units ranged from ¥16500 to ¥22000. The ¥16500 unit was a red model listed with slight screen discoloration and a missing stylus, while the other ones were almost scratch-free.
I spent about 30 minutes deliberating before asking to test the ¥16,500 one. To my surprise, it was basically flawless in-person. The minor discoloration was barely noticeable, especially considering the ¥7,000 savings. When I asked if they sold replacement styluses separately, the store assistant was kind enough to just give me one for free! Since it was the best deal I'd seen all trip, I pulled the trigger immediately and walked out paying ¥16,500 ($105 USD).
Back at the hotel that night, I went straight to work modding it. Since it was a JPN region model, I region-changed it to USA, loaded up a few games, and fell in love with it. It might not be the XL model I originally set out to buy, but I couldn't be happier with how it turned out!
