susu2k ... the Sony is a good projector and the panels do not fade so quickly. I have a Sony projector that is more than 4 years old and the picture is still great. If you like the picture of the Sony AW15, go and buy it.
I think you won't get any further help here or in any forum for your question. You are the one who has to decide for yourself, finally. And asking the same question again and again won't bring you further. As CaspianM said, now you're on your own. Decide, buy, enjoy. Nothing more to say from my side.
