Not true. Do you work for an electronics retailer?
I do not. I just have spent an ton of time reading reviews of and going to stores to view televisions when I bought mine. I have ****** off a few best buy employees by exposing their lack of knowledge of their own models.
Show me a 50"+ television that retails for < $800 outside of Black Friday or clearance worth getting. You will almost always find a minimal number of HDMI inputs, very poor motion handling, poor contrast, or poor color. I am not saying it is unwatchable, but they are not very good TVs.
Also, to everyone reading, please find preferred settings for your TV online if you are not going to get it calibrated. I get bad looks in stores because I tend to go around changing their TVs to movie mode so they will look at least close to accurate. Do not use dynamic or vivid modes. I have left a bar before because the TV was configured wrong and looked like absolute crap. Also, disable or minimize any motion smoothing/edge softening features. They make the image look wrong.
Also, never transport a plasma by laying it flat. This can increases the likelihood of damaging the TV during a move.
