I just need to buy a charger for it, and I've seen usb chargers for a dollar.
*edit* Looking at that listing again, it says "for parts or not working" at the top, despite it mentioning in the description that it seems to work, including pictures of it working... might look elsewhere
The description for the last one at least specifically states that it DOES work, but that the touch screen is desensitized to the point of impracticality.
Does not include battery. DS system works normally but has a broken hinge & the corner has a chip out broken off it. Screens & outer body are in very good condition. Does not include stylus or charger.
