Only the Eizo CGs have built-in calibration sensor and hood included. Prices start at $1900.
Eizo CX/CS and NEC PA all come in different editions, with/without calibration software/sensor.
My personal recommendation would be either Eizo CX with ColorNavigator included, but no sensor - or NEC PA with SpectraviewII software purchased separately. Then get an i1 Display Pro to go with it at 230 extra. Best sensor on the market and maximum flexibility to use on other displays (bundled sensors are locked).
Either way you have to get the hood separately. Another 180 or so there.
The Eizo CX series has a built-in "maintenance" sensor, which should not be confused with a full calibration sensor. It will maintain your calibration targets at set intervals, but for a full calibration/profiling an external sensor is still required.
