I'm wondering if any of you have switched from a DLP projector to an LCD projector? If so, was it for any reason other than seeing rainbows? How did it work out for you? I have the Infocus X1 and am considering upgrading to the Infocus 4805, but I've been reading about the flicker problem and I'm not sure now. Does it affect all 4805's, and is it a minor thing? I'm also considering an LCD HD projector like the Sanyo Z2(great deal now) because I do watch some HDTV also. Has anyone compared the Z2 and 4805? Thanks.
