Seeing as many people are starting to regret their 3DS purchases, you won't have to worry about those feelings with this cheap alternative. Lego model-maker legotown44 recently designed one, complete with folding top, and he's also posted a full instruction guide for you to build your own. It can be found at his instructables page here.

Someone just needs to make a version of this that'll play Devil Survivor Overclocked, and then I'll never have to worry about buying a 3DS.
