I use the Eizo 30" SX30301W for general use and I'm thinking about one of their ColorEdge monitors.

If you're interested in precise colour calibration, it's worth looking at the ambient lighting and decoration in the room in which you work, both of which can change your preception of what you see on the monitor. A monitor hood - such as on the ColorEdge monitors - can reduce the impact. My own monitor sports one made of cardboard painted dark grey on the inside. It will not win any prizes in an interior design competition...
