Hey all just wanted some feedback on a couple mods. First the M3i that works on the Ds lite and DSi. And second the R4DS that only works on the DS lite models. The R4DS is only 10 bucks CDN and supposively works on just the ds lite. And the M3i works on bothe but is more like 30 CDN. I was thinking of getting a couple R4DS.s for my kids 2 ds lites and a M3i for my girl that has the DSi. Any help on this decision would be appreciated. Thanks in advance.
