Help me someone who knows!!
My girls want an xbox 360 for Christmas
., primarily for minecraft but I think they will use disney infinity also. We are not huge gamers , they have a wii used for mario racing mostly and Nintendo 3ds, and iPods which they use mostly for minecraft!

I know some models of 360 are problematic with red ring, but I can't figure out the difference between all the different models.. Trying to pick it up pre owned but don't know what I need! I guess decent storage and wifi is essential.
Appreciate any help!!
