Hi Guys, Please help me - I have been doing my research and sending posts on this forum over the last couple of weeks. I am in the market to purchase my first projector and was more or less decided on the optoma h79 (source denon 3910). I have been told by my local dealer to look at the Sanyo Z4 before going down the line of DLP and so auditioned both back to back today. I admit that I am no Av boff, but take an interest in getting the right kit. I admit that the blacks on the optoma were better and it was quieter. The image seemed to have more depth as well. However, the Z4s colours were superb (only saw it through a denon 2910 and hdmi) so can not say what non hd would be like. I have to say that I could not really notice enough increase in quality to warrant the cash. Am I missing the big picture here (sorry no punn intended). What are the main advantages of an optoma h79 over Z4? What about a lumagen scaler with the Z4 - its still cheaper than an h79? Please help me - I am driving myself insane.
