I think for me one of the biggest advantages of a crt is the refresh rate modes. I with a LCD, even the good 120hz ones, they will only have a 120 hz refresh rate at their native resolutions. so if you like to play at a different resolution that is different the the native one , your screwed at play at 60hz. I have an old sony trinitron and at 800*600 i can play at about 12 different refresh rate modes.
even then all crts are not created equal. you really need to find a nice one. look on craigs list many people are giving them away for free. at one point i think I had 2 extra spares. one I picked by the curb and snatched it up as i was driving by.
