Sorry to snip here, but C. David's comment is/was:

A good comparison is Gretag Macbeth's EyeOne and ColorVision's Spyder. The
Spyder is an inexpensive, durable, emissive only colorimeter. It does not
require special handling or recalibration and costs less than half the
price of the EyeOne emissive only model. The monitor only EyeOne is an
emissive only Spectro and needs to be treated properly, and sent back to
the factory every year for recalibration and adjustment.
I disagree. We have an EyeOne, which is essentially the same device as the
Spectrolino (of which, we have many.) The only devices that have required
"special handling or recalibration" have been the ones that I've punted a
few yards. I do not have ColorVision's Spyder, but do have other (older)
colorimeters. I have not had the same luck with those devices.
Also, be aware that a device that uses a more complex set of filters, or a
diffraction grater (such as the EyeOne) may be more appropriate for certain
markets, such as printing inks, paints, plastics, or textiles, that may
utilize more than typical additive or subtractive colors.
