Also, there have been recent complaints that the black level from this native DLP unit just isn't what it should be. Acer has truly gone entry level, and apparently this projector exemplifies that.
Quality for cheap can be had with the Optoma HD20 (also DLP) for about $100 more. Or the entry level Panasonic AR100 (bright rooms) or Epson 8350 (traditional theaters) can be had for just about $300 more.
I would recommend, at this time, any of those three projectors over the Acer for image quality and overall satisfaction.
