From the brochure for the Spyder:

Virtually all-home theater displays offer visual menu adjustment sliders: Brightness, Contrast, Color, Tint, and Color Temperature Presets. However, they rely on the viewer’s eye to determine whether the settings are correct. This can lead to inaccuracies because people see color differently. The perception of color changes based upon lighting, seasons and other subjective conditions. Datacolor SpyderTV has fully automated the process, applying scientifically-based adjustments to each control in order to achieve more accurate results. It’s the next best thing to hiring an ISF certified calibrator.

$250 USD to adjust sliders in the user menu? I must be missing something, particularly since calibrators do more than that.
