After a long concederation and online google research regading the following DS Cards Nintendo DS/DS Lite R Adapter with a 2GB Memory card
and
M3 Real Rumble Pack + 4Gb Micro SD card and still not knowing which one would be best I have decided to purchase 1 of each for each of my kids.

Well now that I have had both and tried both, I must admit that the M3 is the easies to install and configure plus it comes with 4GB memory card rather than 2GB for R4.

This is my experience and my thoughts, any comment?

Got an M3 DS Real about a year ago, and never had any problems (touch wood), so would definitely recommend it. Personally I prefer the fact the M3 DS Real supports mirco SD cards, and not built-in (limited) memory.
