You won't find them anywhere as new titles, and places with used sections like EB just don't give it the shelf space anymore
Jesus, I know what you mean. I don't have one nor will I buy the refurbed one coming out. But I found a DVD/game shop in the little neighborhood I'm staying at in Tokyo that sells used DC's. They're selling those for around $90 (all excellent shape, but is that a going rate for the DC still??), but the game are really the premium items - like around $45-60 for the better Japanese games.
