I bought a n3ds a few years ago, solid purchase. Emulates almost anything from before the 3ds, and the homebrew/modding scene is fantastic.

Today I hacked my 2DS for the first time. This can be challenging to do, depending on how technical you are and how much experience you have in this field. The process is long and can be complicated, one has to be very careful and use commandline tools and so on. If you are unsure, ask a friend who knows this stuff to do this for you. Otherwise if you do something wrong, it could brick your system or you loose your data.
