There are 9 used 65" VT50s on Amazon right now. Is that a lot? Customer ratings are a better indication of customer satisfaction than the number of used sets available. Having 4+ stars is pretty good in my book, especially given the fact that a dissatisfied customer is more likely to rate a product than a satisfied customer. That said, plasmas are more reflective than LCDs, which is the trade-off of off-angle viewing. They do consume more energy but not by that much.
My buddy loved the set, but not how it was heating up his apartment when he tried to get the Brightness up to watch the set during the day time!
Sent back for a Sharp LED that's bright, and runs cooler during the day.
