I have read all the reviews and they seem to give the edge to the Z4 over the AE900, but it is really "a soft suggestion". I guess at this point the warranty on the z4 would probably push me to the Sanyo if nothing else. I did see one article stating that the AE900 is better than the Z4 for pixcelation? Can anyone expand on what that will mean on a 120" screen with a 20' viewing distance? Are there any other issues I should consider when making this decision between the two? This is my final post on the issue prior to buying. I do have one final question. Are the 900 and Z4 significantly improved enough to justify the $700 difference in price? I am a newbie at projection, but am on a budget. Would the 700 satisfy my needs just as well? Could I tell a significant different between them if I am not a real "hardcore" videophile? Thanks for your final input in this matter.
