Review of the official case for the Nintendo DS, a great little case to carry your DS system and several games.  It’s compact, and can also carry Gameboy advance games.  Overall a great case if you have a small game library.  If you have a large amount of games, you will probably want to look into a bigger case.

A guy buys a case for a DS Lite off of eBay and is not very happy with it. I think the moral of this story is to check an eBay users feedback and make sure they have good feedback for the same case you plan on buying.
