LG Electronics (LGE, Korean: LG전자) (KRX: 066570, LSE: LGLD) is the world's second-biggest maker of televisions and third-biggest maker of mobile phones.
I just purchased this LED projector from Amazon and it does ship straight to Australia. It is only $50 cheaper than other US sites, but it is the cheapest I can find delivered to Australia.
This model VR5902VLM is the second generation of the LG roboking. From all reviews (youtube+whirlpool) it seems much better than the IRobot Roomba and Samsung Navibot.
