Like "Glider" above, I use the Spyder2 calibration system on my LCD and CRT monitors, and have been very pleased with the improvement in color accuracy. I take photos of small items (such as jewelry and art glass) for posting on the Internet, and the Spyder2 system has been very beneficial in assuring color accuracy. It's very easy to use, and if you shop around on the Internet, you can buy it for about $135-140.
