By "non-Wega" do you mean "non-Sony," or are you looking for a Sony that isn't a Wega? If it is the former, I believe there are many TVs that perform the squeeze trick, including Samsung.
I think he is looking for ones that have a 16x9 "mode", not ones you have to squeeze through the service menu. I far as I know non-Wega Sony's do not have this option. I know Samsung sets have it. I didn't think Toshiba or JVC or Panasonic, or any others have a "mode" without going the service menu route. I am assuming he is also talking about NON-HDTV ready sets.
