I've not been too much into color calibration, though I should have been. I picked up a HW calibrator a while back, but it's limited in how it could improve my MBP 13" screen. I just received a Dell U2311H from Dell (of course). Great screen. 23" Landscape and portrait tilt. Easy menu controls. It's an IPS panel, though it uses a color interpolation, and is native only 6 bits. But still, it scored higher in the online tests I found than pricier counterparts. It's only been out since last summer, but is getting good reviews, and good testing. I called Dell because they had it listed at $319. I asked for a lower price, and they gave me $277 (but they do charge sales tax). If you are looking for a budget end, but reasonably good monitor for photo work, take a look at this one.
