About 5 years ago, I picked up a Sony G500 21" crt. It is fantastic, and knock on wood, still going strong. It weighs a metric ton or three, heats my office nicely in the winter, and takes up a lot of space on my desk. But it kicks virtually EVERY LCD monitor's ass in image quality, even on text. I'm an engineer, I do CAD and motion capture analysis on my computer at work, where I have dual 19" LCDs. I don't recall the model/brand of the LCDs at work, but they are pretty high end. They look like SHITE compared to my G500 at home. Plus the argument about native resolution on an LCD is really important. With a good CRT, you can use virtually any resolution you want (that's supported by the monitor). On an LCD, if it's not the native resolution, it generally looks crappy.
All that said, low-end CRT's suck more than mid-range LCD's IMO, because of geometry problems. But if you can find a truly high end CRT monitor in decent condition, it'll walk all over any LCD for any price.
(BTW, I was exaggerating about the heat. It's not that bad. But it is big, and it does weigh a lot.)
