Pros: it's the official and original ColorHCFR colorimeter and totally supported. Really quick readings -maybe the fastest- even in difficult conditions such as low luminance patterns (IRE 10, 20, 30).
Cons: it uses a calibration file to properly calibrate. So it may be incompatible with your display/proj. for a while until the file is available.
Price: possibly inexpensive if done correctly (by a professional in a group buy), or expensive if you DIY -and have no tools or knowledge to begin with-. So it depends on the conditions, from $50 to infinite...More info.Colorvision Spyder2:
Pros: the cheapest colorimeter. It may be labeled as "entry level" but it's an accurate probe just perfect for the calibrator on a budget. Totally supported.
Cons: the slowest, especially in dark patterns. Also inconsistent at those low IRE levels.
Price: the colorimeter (hardware) is part of several Colorvision packages. So it starts at $79 msrp in Spyder2 Express
.Xrite DTP-94 (AKA Monaco Optix):
Pros: quite fast, it is a very accurate colorimeter. It even has recalibration (internal offset calculation based on the temperature). The most recommended by the ColorHCFR team. Totally supported.
Cons: more expensive than Spyder2 and discontinued, still one of the best.
Price: from $219 msrp in Monaco Optix Xr
.Gretag Macbeth/Xrite/Pantone Eye-One Display2/LT:
Pros: since Xrite and Gretag Macbeth merged this is supposed to be the replacement for the DTP94. Probably as good as the Xrite. Now fully supported.
Cons: also more expensive than Spyder2.
Price: included in several packages. From $170 msrp in Pantone Eye-One Display LT
.Gretag Macbeth Eye-One Pro:
Pros: really accurate, unlike the others (which are filter-based) this is not a colorimeter but a spectrophotometer. As it's name implies this is a more professional tool (needs to be recalibrated regularly). Totally supported.
Cons: really expensive, not necessary better than a good filter-based colorimeter in real world calibrations.
Price: did I say expensive? From $1095 msrp in Eye-One Beamer
