The LG pa75u or the pa70g would be much,much better.
The asus has 1 year warranty, the LG has 2 year warranty
The asus as 2 (2watt speakers) the LG as 2 (3watt speakers) The LG has kick ass speakers, you really have to hear it to say "wow that's good for such a small device".
The LG pa75u as 3d native, wifi, bluetooth, smart apps, built in tv tuner, 2 remotes and is cheaper than the asus b1m.
The short throw on the asus could be good or bad, depending on your setup situation, for the pa70 (4 feet back makes 40 inch widescreen, 8 feet back makes 80 inch widescreen.
It could be a good PJ, only 1 user review on amazon and none on newegg, and no user reviews on youtube. You can review it for us, if you buy it.
