The definitive HDTV buyer's guide?

The main thing that bugs me about my plasma is the image retention issue.. If you leave something on the screen for too long, such as a paused DVD, the screen will retain that image until you've watch enough other content to wipe the image away.. And eventually the pixels in the screen will wear out and the picture will become dull.. LCDs don't have this issue..

I have a 42 inch Samsung plasma and it has a feature that lets you clear out the pixels or "clean the screen" to counter any kind of burn in. There are two seperate versions of this on my tv, one that goes all white and washes it out...and one that does a black screen and a white line pans from right to left cleaning the pixels. I'm not really sure if other products offer such a thing or not.
