I purchased Colur Munki a few months ago. When you buy your monitor it is set up to look good in the showroom and is not necessarily calibrated to produce accurate colour prints. When i used ColourMunki the first time I was amazed the difference it made to the monitor display. The windows back ground photographs had detail in the shadows and highlights that I had never seen before, and the colours in colour prints from my Epson where much closer to that shown on the monitor. ! Colour Munki even adjusts the monitor automatically for ambient light. You can also calibrate projectors, though I have never tried this.
Well worth the cost if you are serious about producing colour accurate prints.
