I was in same situation Oct. 2006. My monitor was going out and needed a new one. CRT vs LCD?. I researched it alot. Never had a LCD before, always liked the CRT. I couldn't come up with a really good CRT and the reviews were good on the LCD. For the price it was the best gaming monitor.
I went with the Hyundai LCD L90D+ (234.52)
What a difference in picture quality.
1280x1024 8ms .294mm DVI-D
Refresh rate 60 Frame rate 60.
No regrets and would definitly buy another one. After having the LCD i would be hard pressed to go back to CRT.
Buy the way my old CRT was a Viewsonic A90F.
