If either of these NEC models are discontinued when you are shopping flat panels, call NEC Tech Support like I did, and ask for a recommendation on a comparable quality picture in the NEC line. Personally, I cannot see myself buying anything but an NEC in a flat panel. I spend too much time looking at my flat panel display to settle for poor quality. (No, I do not work for NEC/Mitsubishi. I am just a self-employed businessman who has benefited from the electronics products online reviews of others, so I wanted to give something back to the online community)
My humble recommendation -- If you value your eyes, and you want superior quality in a flat panel display, take a look at the NEC line before you buy.
