i do not suffer from the "rainbow effect" as far as i know.
my only purpose (and i guess everyone's..) is to improve the entire experience to be more cinematic and to actually "be more in the movie"...
so, do you think upgrading to the sony do the trick?
I'd be curious to see what others think as well.
Honestly, if your room is mostly light colors and you may have lights on occasionally that hit the screen at all, I don't think it would be worth the money to you to get the Sony. The Optoma costs much less than the Sony, but I think might be pretty much just as good. You might notice a slight improvement in black levels, but that can be eaten up quickly if there is any back reflection on the screen, which can happen in a light environment.
I've never seen the Optoma in person - so I can't speak from experience. You may want to see if you can find a place to audition the Sony - they have the HW40ES at most Best Buy stores with the Magnolia theater outlet - which if you were considering a Sony I think would be better for your situation - it puts out more light at the slight expense of contrast in some scenes. I'd also consider some of the Epson projectors too. I think the Epson 3020 or 3500 projectors might be able to give you a little more color pop without popping the budget, and they'd be similar in brightness to the Optoma.
To get one of the high contrast projectors like Sony HW55ES or the Epson 5030/6030, I think you need to have a well controlled room where there is not much back reflection on the screen and it really is pretty dark.
All that said - if you did get the Sony I think you'd like it, color is great, contrast is great, performance is very good, and the pixel structure I really like if you get close - but it would probably not be as bright as the Optoma, and you might not like that, that said it would definitely be bright enough for me on a 106" if the lights are off even in a light colored room. Another thing to consider - the Epsons come in a white case, and if your room is light colors you might like the white case. So its a great projector, just not sure that you'd see the value from the extra money over the mid-grade Epsons.
Again, never seen an Optoma in person though - hoping others might say something. Nothing beats auditioning - if you can find them, which isn't always easy...
