I owned the HLP-5063 for about a month before returning it. The screen had few defects which I found out were inherent to every DLP they make (blemishes minor enough to escape QA, I guess), the rainbow-effect disturbed my viewing pleasure, and the upconverting of SDTV was terrible. It was big, it was colorful, but I'm not sure it was worth the price. I exchanged it for the 46" model, hoping to escape the flaws, but it still did no good. My friend bought the 61" and returned it for the same reasons. I'm much more happy with my Zenith plasma now. DLP has potential, I'm just not so sure that any DLP under $4,000 is worth buying right now. Give 'em another year to iron out problems and bring costs down more.
