hahahaha nice to have met another who started with a PJ at the grass roots level. Cool you have me hyped for the 5050! Thanks!O my you still have a AE900u' You might wan to contact the Smithsonian to donate it for their collection. I started out with the ae900' it was a nice FP back then. Then I upgraded about every 2 years and sold the old one's here. You will blow your mind with the newer Epson or Sony ect. The contrast and color is so above your ae900 now . Also Epson 4k pixel shifting is so good that I do not worry about it being native 4k. Every review says the same. The real reason to upgrade is Contrast and color for me. I still use a Epson 5300ub and love it' I only have 300 hours on it and will keep it for another year. Then see when the price of the 5050 drops. I know my signature says I am new but I been a member since 2005 due to lost pass words and new computer. And I would not worry about it being Native 4k or pixel shifting.
