do a ton of research before buy . could not find all the feature I want , so I wait . -lrb- go from 52 '' rca rear projection tv to 92 '' projector . -rrb- glad I do , this unit do a great job in a room with ambient light . I recommend get a light gray screen rather than white or just use the wall for improve contrast . excellent quality , quiet , great picture . remember , the screen be only half the experience , do not skimp on sound !
