Get LCD. They look sooo much better. Both are around the same price, a nice 19" LCD is around $200, you can't go wrong. The argument used to be that the response times for LCDs were much higher, which causes ghosting, but nowadays, that isn't a problem.
I'd recommend one of these 2 LCDs:
20.1" widescreen - http://www.newegg.com/Product/Produc...82E16824112006
Also, I forgot to mention, when the size of the monitor is measured, for LCDs it only counts the viewable area, but for CRTs it counts both the viewing area and the "frame", so a 19" LCD has bigger viewable area than a 19" CRT.
