Big Lcd Projector Has Anybody Tried To Build A LCD Projector?

Has anybody tried to build a LCD projector? - big lcd projector

I have on several different sites, how to build an LCD projector lenses reflect more light bulbs and a fan. My question is how many people have done this and how is the quality of the image? I have no doubt that I build it, I can not make the effort and then with the image of aspiration. Also how big the picture can, however, no shit? I have a 54 "TV now and if the picture quality not as good in large sizes, so I do not want to build.
