Have have this for 10 month and it have perform flawlessly . even have a few power outage that shut it down unexpectedly and it still work great . on a 135 '' screen and seat 12 foot away , the picture be great . maybe 1080p would be better but most of what I watch be not 1080p and for the price and lamp life , you can not beat it . more hdmi input would be nice but you can always buy a hdmus switch . I only watch it on eco mode and the picture be great -lrb- window be completely black out and only ambient hall lighting from downstairs -rrb- . even with light on , it do not totally wash out the screen . I be very pleased with this projector and it should last I a while until 1080p projector with longer lasting light source come along -lrb- at a reasonable price -rrb- . do not know about 3d because I be a cheapskate that will not pay $ 100 for glass .
