S-Tek uses an electric gyro which replaces the turn coordinator. Century's
gyro is vacuum powered, and replaces the gyro horizon. With the Century, if
the vacuum fails, you not only lose your primary gyros, but your autopilot as
well.

Speaking for the S-Tek, I can not see where it would be much harder to install
later. The biggest difficulty would be installing it in the panel.

Unless I am misinformed (or the products have changed since I bought mine),
Century would not be an option in an airplane with no vacuum system.
