I second Art on the color calibration software. But (in Europe) the 4870 also came with a bundle, a Gretag MacBeth. Not bad. We bought the 4870 when it was just out (and still expensive), but are extremely happy with it. Saves us lots of time and cost. We got a used (cheap) Monaco screen calibrator later. So no IT8 target, but we don't miss it, really. Perhaps you can find a good deal on the older 4870 + Gretag bundle...
