I would honestly go for the M3i Zero, mainly because since it is a new card coming out, even if there are some bugs at first, it will no doubt be compatible with the expansion cards on the DS Lite plus you will still get firmware updates for a much longer time period then the M3 Real will, I have a feeling that eventually the M3 Team will pull the plug on the M3 Real in a year or two in favor of the M3i. I mean the M3 Real bundle pack is still around 40 dollars depending where you buy from, whereas you can order the M3i Zero for 27.99 on Gamezway for now, then the price will go up after release. Although you would have to buy the slot 2 cards on their own, since you can only get them with the M3 Real.
