They are good now, even when they first came out DLPs had that annoying rainbow effect on a black screen. That is no longer an issue. Unlike CRTs and Plasma, DLPs and LCDs are immune to burn in patterns !From what I understand the LED tvs have excellent life span. The downside to LED was they had issues producing a picture competitive to the current high end TVs.
That issue being resolved they look like a really nice option.
