I replaced the lamp in my Epson 6010 last night. Brief history - at about 1,600 hours or so, the lamp started to flicker in "Eco" mode, and ghosting got a lot worse. Going to high lamp mode solved the flicker problem until I got to about 2,000 hours, when I started to notice flicker again. 3D quality degraded along the way, similar to the JVC but not nearly as bad. I expected to get "like new" 3D performance after the lamp replacement, but that hasn't been the case. Light ghosting is still very, very good, but dark ghosting (branches or highly contrasting dark objects against a bright background) is much worse than it was when the original lamp was new. I don't know if this is a lamp issue or a projector issue. It was disappointing, though. I'm hoping other Epson users will report their experiences when they change their lamps.
My go-to Blu-ray for dark ghosting is Monsters vs Aliens, especially Chpt. 7, where the president walks up the stairway to the alien robot. On the original lamp, I don't recall seeing any ghosting at all, but it was very noticeable in that scene last night. Overall, though, I was struck by how very good 3D still looks on the Epson. I use medium glasses brightness, and the image looks very bright on my HP screen. Contrast is not nearly as good as the JVC, obviously, but the lack of ghosting in general more than makes up for it in terms of the overall 3D experience. Recently, I started reading the BenQ W7000 thread and other comments about that DLP, and there seem to be a lot of issues with it, too, depending on the luck of the draw. I'm loathe to trade one set of problems for others, so I'm inclined to try to keep to my original plan and wait until the Red laser is released, or at least until next year. I may not be able to keep myself in check, but it's probably the wisest course.
BTW, I was saving my 2 year old JVC RS40 for a family member, but that looks like it's fallen through, again. It has a brand new lamp, 4 sets of Xpand 103s and a few other goodies for a good price. PM me if you're interested.
