I have an m3real and I was rather happy with it until recently compatibility went down and what unopepito said happened. Also the microSD spring broke after a few months; I was able to fix it, but in the process of opening the cart up a few times some of the plastic clamps broke and now it´s rather wobbely. I´m going for an AK2i too, mostly because I´m about to upgrade to a DSi, the cycloDS is also often recommended for the original DS (lite).
