CRT here.  I had an old NEC LCD that was great for basic, everyday use, but for artwork, it was awful.  It had pretty bad color banding and AA problems even at the native resolution.  I finally gave it to my sister and switched back to my old 19" CRT even though I barely have room for a cup of coffee on my desk now.  Some of the newer LCD's might be ok, but I'm going to have to see it in action before I plunk down the money for one.
