Sorry Tvad...bought the TH-50PX600U. I got a great deal on it as well. I considered the commercial panny but once I added the extra HDMI blades I wanted, plus the stand and shipping, the consumer TH-50PX600U was nearly as inexpensive.
Easy setup, beautiful contrast, good upconversion for standard broadcasts.
My only worry is that my neighbor warned me that all plasmas lose their "gas" charge within a year and have to be recharged at the factory. When I pointed out that this - like instant plasma burn in- was another plasma urban legend, he assured me that the guy who sold him his DLP swore it was true.
Gee...I'm sure I'll learn my lesson when my year's up :)
