I've had the Samsung HLN507W for almost a year now and have very, very rarely seen the rainbows and never gotten headaches from viewing it, even after 4-6 hours of movie watching. I love the PQ, especially HD, but even SD looks great.
I initially set out to get a plasma to complete my home theater system, but after two years of research and looking at plasma, RP-LCD, FP and RP-CRT, one day I came across a DLP. I was amazed that it had a PQ that was equivalent to the Mits plasma I'd been contemplating buying. Also, as I continued my research, DLP doesn't have the drawbacks of gradual plasma fade or pixel burn-out potential of LCD. So, I ended up buying the Samsung DLP and have never regretted it. It's been a terrific monitor.
