I remember when 'Hey you Pikachu' came out. It was $90. Did I buy that mess then? Heck no. I waited it out and a number of months to a year later, I bought it new for $1.95. Same thing with that Gameboy advanced Wireless attachment. You could get one used once at a Gamestop for under $2. I imagine Nintendo will utilize this peripheral more than others in the past, but it's their model of "Buy this attachment and use it for a couple games, then it's support is discontinued" that makes me want to buy used.
