As for monitors I'd still not use an LCD for colour work, especially dark scenes, but if going that way, the Eizo is an excellent screen, but do they still make it? I last used one back in Christams of 2003!
The 213T isn't bad, had good colour but struggles down around IRE30 or less, it must also be hard to find now, I haven't seen one for over 2 years. I used one for a while for vector work, but found it useless for video editing - although the colour was acceptable the detail went to smearsville when scrubbing video back and forth - my guess is the response time was just too slow.
The 204b I haven't seen.
The spyder does OK on LCD screens, but can give inconsistent results at the darker end, make sure you run the calibration a few times to check that you are getting a reliable calibration.
