I'm trying to "de bunk" what a salesman told me. He said he preferred the LCD RP TVs over DLPs because the DLPs have more moving parts that could lead to problems. He said the spinning color wheels are "mechanically complex". This seemed like a used car salesman telling me he wouldn't get a car with power windows for the same reason. I didn't see rainbows on the DLP sets I looked at. How obvious are they if you do? Do you need to squint and hold one foot up in the air while leaning to the left...or is it more obvious than that? I was leaning toward the Sony mainly because of the 25 year old 19" set I have that won't die. But I'm open minded and when investing this much want to make the right decision.
