I currently have a Sony 36XBR250. I love it, execpt it only does NTSC. It has a great picture for cable and satellite. I am looking to upgrade to a 42" 16*9 display. I want a 42" because it has about the same picture height as my 36" tube and I think that it is a good height for my room. I want to be able to watch both NTSC and HDTV. My question is, when I watch NTSC (with black bars on each side) will a 42" plasma look as good as my 36" tube does now?
