so far this have be a good buy . I be Mark Tucker , the assistant pastor at Old Orchard Church in St. Louis , MO. . this dp be a great find because it do exactly what we need it too . we do not need the extreme high definition image , but we want something that look good and enlarge well . it do get a bit hot after 2 hour of straight use , but I be not sure that this be a problem . the price point be excellent for we as a small church , especially since I get it as a Open Box discount . I love the option and the keystone feature .
