Need a new calibrator?

The ColorMunki Photo is a true spectrophotometer and can build both monitor and printer profiles, hence the $450 price tag.

If all you need/want to do is to calibrate & profile your monitor (no printer profiling), you can go with either the ColorMunki Display (~$170), or the i1Display Pro (~$240).  While the reviews of the ColorMunki Display are good, the reviews of the i1Display Pro are superb.

Note, I don't have any ColorMunki product, so I don't have any first-hand experience with the ColorMunki products.  I have the older i1 Pro spectrophotometer (~$1500 when I purchased it 6 years ago), which does both monitor and printer profiles.
