CRT monitors are definately still better for image quality, but LCDs are quickly gaining ground. I think in a few years nearly everyone will be using LCDs, but until then, you're probably better off using a CRT (that is if you don't mind a bit of radiation
) Personally I've always been partial to NEC CRTs because of their excellent image quality and reasonable price.
On the other hand, if you're really picky about refresh rates and flicker (like me), you might be better off with an LCD. The main advantage an LCD has over a CRT is the fact that you never
see any flicker because of the way the picture is displayed. Once again, I'm pretty partial to NEC displays, mostly because I've been so satisfied with mine. However, I've seen some very nice products from Viewsonic and Samsung, so the absolute best way to make a decision is go into a store and sit in front of it yourself.
