I would love to get either a new Sony or Samsung 40” LED LCD, 1080p, 120hz, TV, but I have a 20 year old 22” Sony Trinitron that still works pretty well and with the scrambler devices for pulling in digital broadcasts, I can’t justify junking it for a new set. Fiscal discipline I guess.
It depends on what you're into. I'm a huge fan of classic films. I can't see enjoying Ben-Hur or Lawrence of Arabia on a square 22" standard def TV.
