Actually, while some LCD's ghost real bad, there are some newer one's that only ghost on stuff that is moving way too fast to see it clearly anyway.
I myself have a Viewsonic VX2000 (20" 1600 x 1200 resolution) The thing is the response time (similar to refresh rate). The responce time is the minimum time it takes for a pixel to darken and lighten fully. The responce time on this monitor is 25 ms. Most LCD monitors the responce time is 50 or more. Basically the difference between this monitor and a CRT is so minimal that the plusses so far outweigh the minuses that I wouldn't go back.
I play BattleFront 1942, Unreal Tournament 2003, Unreal 2, Medal of Honor, SFC2, OP, and 3 on it and it is great unless I do a fast spin in a first person shooter. Then it will depend on the game. UT2003 the only ghosting I ever noticed was with bright red spots. They would ghost ever so slightly with a super fast pan. Other wise the 600:1 contrast and clairity blow away any CRT, plus, it is FLAT!!!. No glare whatever, everything is super crisp and clean.
Note that I am driving it with an ATI Radion 9800 pro with the DVI port.
Been thinking about adding a second one for double the desktop space.
