Don't fancy the 'New' 3DS? Well how about the wedge 2DS model with Mario Kart 7 for £79.99? Sounds like a plan to us, especially if you're not bothered about painful headaches / 3D visuals. The lack of hinges has also proved popular with parents of clumsy children.
Don't forget, you could knock some extra money off with your reward card if you built up any additional points over Christmas. You can't take them with you after all.
