I just recieved my 3DS a few days ago. I am in the process of getting a few necessities for it though. I already got screen protectors and Stylus... Stylus'es... Styli? Anyway, I am also getting CTA's External Battery pack. I want a protective case, but not one that will obstruct the attachment of a charger or charging via dock. I also Like the old Backpack-like cases that were for the old DS's. I loved those, but I do not know where to find them or buy them. Please list some recommendations...
