I second the advice to get an R4... the m3 simply to the best of my knowledge is being replaced by the m3ds real, i have not tried the simply, but have the real and r4... the m3 has room for improvement, the r4 is solid, reliable, and to me between the two, just plain funner all around! the only other choice i would consider would be the cyclods... but i have yet to try them, they are more expensive, have heard mixed things on the cheapness of the build, but heard great things about the interface... but get the r4 and you will be more than happy...
