Thanks nevertheless. I wouldn't be able to purchase from that website anyway, I'm British.
I can't measure his room but it's small sized. I won't buy one now but I'll buy one next month, and I'll buy the one you linked to me. I'm going to rearrange his room so I can build a little shelf for him to put the Projector on, I just hope that for the £320 That it costs we both won't be disappointed. And as I said the color of his room is a clean blue, meaning there's no bumps in it, but it's not clean if you know what I mean, as in it's not blank, there's some sort of pattern on the wallpaper, I just hope that because I'm not going to be buying a screen that won't affect the quality too much. I gave him my brothers old 32" LG LCD TV anyway, but like you said nothing compares to 120" Of awesomeness.
