1. why need other people to tell you worth or not worth?
for me it's totally not worth owning a 3DS... why?? every time there's a nintendo direct I will be cursing my self why all those attractive game coming out so soon my wallet is not ready..

2. you told us that you already do the research then put your research in used.

3. Best deal usually comes online.. Here we got plenty of seller like Kyo, PBBseller, David and many many more... All of them give good deal...
and here is a good play you can get start
