RRP: $2500, next best price seems to be LG themselves at $2000. 40% off a new portable (1.5kg) 4K projector that was only released some months ago. Can project to 120" with a throw distance slightly greater than 3m. But most reviews say for best picture quality 80" is good.
Other LG projectors are also heavily discounted:
