I just purchased the Mitsubishi WD-52525 DLP and it's totally awesome. The Mitsubishi doesn't produce these “rainbow effects” as often as other DLP sets, but if you've got a trained eye and know what to look for, they show up occasionally. However, most who have viewed this tv can't even tell. There's a review of this tv on my website you can read, along with a review of the Samsung HL-P5063W. If interested just click on my name then the link provided.
