I have be use a front projection setup for several year now , start with a serendipitous purchase of a NEC lt150 that be a `` price mistake '' find . after get it and figure out how to mount it , put up a screen and run cable in the ceiling with a friend 's help , I have be hook on the true theater type experience that a projector provide . it be a dim , loud , business class projector but still a thrill to have a 100 '' picture . I upgrade over the year to a brighter NEC business projector , then finally enter real home theater projector land with a 1080p optoma hd80 . at the time , the hd80 be one of the best bang for the buck projector ever make , and I enjoy the heck out of it . one of the thing that bug I with the NEC business projector be the dreaded dlp `` rainbow effect '' , and with the hd80 that be minimize enough that it never really bother I . I be fairly sensitive to it , apparently , and could force myself to see it on the hd80 but only by unnatural thing like shake my head . unfortunately after 2 1\/2 year the hd80 die , and I decide to look around for new model since 1080p have become the standard , and less of a premium feature . the Benq W6000 be high on my radar because it be one of the very few moderate price dlp model that include lens shift . its brightness be another attribute I like since I have a `` living room ht '' without full light control , and the extra brightness be great for those afternoon football game . I end up buy a Epson 8100 lcd unit locally , and the w6000 here , and compare they -lrb- eventually add a Sony SXRD model to the mix to hit all 3 major projector technology -rrb- . the Benq live up to its billing , produce a very bright , dynamic picture . after some tweak to the initial base setting , I be pretty happy with the overall picture , color , black level etc. . as another reviewer note , Dynamic Black seem to cause a little too much iris noise so I also turn it off , and do not notice much difference in the overall picture . but one problem come back ... rainbow . the color wheel be actually only a 4x speed , as oppose to the 6x speed that the hd80 use . in addition , extra brightness seem to make ANYTHING more noticeable , rainbow include . after a couple of week , I just could not live with it and end up return it . if you be not sensitive to this artifact , the w6000 be a fantastic projector . I really , really want it to work for I but end up pay more for the SXRD unit -lrb- Sony vpl-hw15 -rrb- . -lrb- I be not overly impressed with the Epson 8100 , though it be a lower price model so not a really fair comparison - I wish I would be able to find a 8500 to try instead . -rrb-
