"I just purchased a Sanyo Z5 from Richard. What an awesome machine. The picture is great and the contrast is just as good as my DLP (Optoma H27). I can even watch TV during the day on a 122"" diagonal screen which is just a white wall (although it is not too bright). The zoom allows 120"" at only 13.5 feet and that isn't even full zoom. Think about it, that is like 9 40"" screens. I was a little concerned about purchasing something so big over the internet, so I ended calling Richard directly. He was great to deal with and offered excellent advice for making a screen. I ordered the unit and had it the next day. I would totally recommend Quebec Acoustic. Richard is great to deal with and his prices are great too. I can't wait for the playoffs in HD. Thanks Richard."
