I only ask, because that console is selling used where I live for about 200-300, but the 3dsxl is only about 100 if you find a good deal usually around 120.
I can second this. I got back into playing my 3DS last year and was quickly reminded how frustrating it was having to keep your head in the perfect spot for the 3D effect to work correctly. I ended up buying a New 3DS and was blown away by how well the head tracking worked and how big of an improvement it made to the experience when playing with 3D turned on.
