I just put a 34HS420 out of it's misery. These "HS" (High Scan) models are HD sets only in the sense that they have digital tuners, not they they have anything resembling HD-quality pictures. What you would want is either the XBR or XS models with "Super Fine Pitch" tubes. I have a 30XS955 with a breathtaking picture. It is 8 years old now and I dread the day it will die. Also comes with a cable card slot so I don't need a cable box and that frees up its only HDMI input for my computer's 2nd display (so it doesn't need any Smart technologies.) You don't get good text with CRTs because of their interlaced displays but video is terrific and colors blow anything newer out of the water. Plus, it handles lower res signals much better than flat panels.
Also, the 34HS420 weighs about 200 lbs!
