I am trying to decide if the latest Sony VPL-HW50ES is worth the difference over the Epson 5020. I have a dedicated "cave" with no light issues. I presently own an Epson 8350. It is projected onto a 120" Carada Criterion 2.35:1 screen with a 1.0 gain. Although I keep the projector filter clean and it is not a dusty environment, I have had problems with dust getting into the prism or LCD panels. Epson was very good with their replacement policy. I purchased the original unit in Dec 2010. I have called Epson and they very quickly sent me a new unit twice so this is my third unit. It is now out of warranty. The dust problem isn't terrible and I'm the only one who really notices, but as they say, once you see it, you can't ignore it. I had thought about stepping up to the Epson 5020 but after reading reviews of the Sony VPL-HW50ES (could they come up with a longer model name with no easy shorthand) and with the internal dust issues with the Epson, I am leaning toward the Sony. In real terms, it looks like the Sony is about $800 more. Is it worth the difference? Does anyone think I would have better luck with the dust issue? I have read some posts that tended to indicate that the dust issue was an inherent problem with the 8350. If so, is that an issue with all Epsons? One other thing I really like about the Sony is the ability to adjust the LCD panel alignment with 144 separate zones. As far as I can tell, the Epson 5020 has no panel adjustment and a slight misalignment was also a minor issue with the 8350.
