The original price for this projector was US$1799. It was mainly produced for the education market, so I can't actually find anything about it from Australian retailers who sell direct to the public, but looking on eBay, there's one listing from the UK selling this model for $1300. The specs seem about right for a conventional projector around this price, but when you consider that it's an ultra short throw projector, it makes it a very good deal. 13 available at the time of writing this post.

Great price for ultra-short throw and the features it's got, but worth considering that it's only 1280x800. The seller conveniently left the resolution out of the specs.
