advice on easiest setup{for my 8 year old}dvdx or?

[martiemcd]

i am about to fit a mod for my 8 year old ,but am unsure which set up would be best? i know dvd region x and neo is simple and he can use it no bother,but was unsure about the usb chip thing{forgotten what is called},and the ar2?i am also going to install it myself,hence the attraction of the one wire solder,but ,is it compatable with region x as the ar2 sounds a bit to complex?if im pretty confident with the solder is it just as well to go for a fully wired chip?help,please and thanks.
