I do a lot of research and it boil down to the pb6100\/6110 or the InFocus x1\/x1a . I purchase the pb6100 and have be plesantly surprise after a month of use . in presentation mode , the picture at 7 foot wide be sharp and impressive -lrb- make sure you select the correct user mode -rrb- . for movie , the picture quality be truly stunning -lrb- must choose cinema mode -rrb- at 7 foot wide !! it appear that the quality of dvd player be rather important as a budget dvd player produce a wash out screen while a good progressive scan player produce rich and vibrant color with no distortion . shockingly good , even with some ambient light . it be a huge payoff for a very modest investment . very enthusiastically recommend .
