NEC PA241W - calibrated for photo work. -Absolutely one of my best decisions ever.
Professional use:
NEC PA301W (main retouching monitor) flanked by Aluminum 23" Cinema display
(Photoshop palettes/bridge/other secondary stuff).
I second the comments on the NEC.
The calibration software works flawlessly and it's the best monitor I've used to date for critical color work.
(Purchased to replace a tired 30" Cinema Display about 5 months ago)
Fun stuff: Old 17"/20"/22"/23 Acrylic Cinema ADC displays running with PowerPC G5's
as music servers around the house.
Not sure they'd be suitable for color critical work at this point,
but they sure are purty displaying itunes/Pure Music and album art.
(and just sitting there for that matter)...
