I am using a Sceptre HD 24" Widescreen LCD monitor. It was a recent upgrade from my Sceptre HD 20.5" Widescreen LCD. Before that I had a 21" CRT and I have to agree that the LCD is one of the best computer upgrades I have ever made. The difference between LCD and CRT is like night and day. The fact that it is lightweight and takes up so much less space is another huge factor that makes them nicer to use.
