I mount my from the ceiling and the throw be perfectly suit for this . my price be 644 and this be a steal deal for that . it be bright , able to use it in a room that get muted sunlight -lrb- closed white curtain -rrb- and unshielded -lrb- naked -rrb- light -lrb- 3 of they about 75 watt each -rrb- . only in dark scene do I see shadow on the screen from wall and such behind the projector . this be my everyday tv screen . I have it connect to dish hd -lrb- 1080i -rrb- and with it project to a width of 9 foot you will be awed . watch football will never be the same . I have use the speaker and while it be weak against my 1000 watt thx amplifier , it be perfectly suitable to hear in a reasonably quiet room . pro : bright , short throw , simple setup , 1080p , good value . con : no horizontal keystone , large , appear fragile , no DVI input .
