Hi there !
I have been chasing the LG PA70G LED Projector since Dec 2012 and I finally got it in May 2013, used it for a week now.
IT IS PERFECT ... FOR 799$ , WORTH EVERY CENT.
It is small enough to carry and it carries a punch ! I get a fullHD image in my bedroom at around 100 inches and 200 inches in the living room for late night family viewing.
When brightness is at full you however have to have good sound so it will not be a distraction. No issue with focus nor zoom.
I am yet to use HDMI, I will when I get a graphics card that can candle 1080p native. VGA is doing okay and the best part is the USB Function that allows quick and easy storage play.
I am not sure which is clearer, via usb or HDMI. My family and friends are speechless and i second them.
This is just the 1st step to building my ultimate hometheater set-up.
I will make a DIY Projection screen in the course of next month and will let you know how that goes.
here are the pics
