I've done reading up on color calibration, but I'm still confused as to exactly what I should be buying. I'm using a Macbook Pro with LED backlight. Apple's LED monitor may be in my future sometime (or something similar) unless there is a good reason against it. I know a notebook screen isn't the best to work with but it's what I have.

Do you have any recommended products or any features I should specifically look for? I've become more interested in trying to print some images and this seems like the proper first step.
