You don't have Best Buys, Targets, Gamestops, etc. over there? I got my N3DS from Walmart.com for a pretty sweet deal. Also are you sure you really need one considering you still have your regular 3DS? Honestly the improvements aren't worth the upgrade, you'll pretty much never use the additional inputs, and the better performance only applys to games that were specifically made with it in mind, which is still only Smash Bros. as far as I'm aware.
Also, why the random WOY pic? :L
