Auto Power-board to Simplify Computer Setup

On the weekend I purchased a Master / Slave Powerboard. This is plugged into a mains power socket and then my computer and peripherals plugged in. The main item of equipment, usually the computer or TV, is plugged into a "master" socket and the peripherals into the "slave" sockets. When you turn on the computer (or TV) everything else is turned on as well. More importantly, when you turn off the computer (or it turns itself off after a set period of non-use) everything else is turned off. This works remarkably well. One use is for vod-casting studios at universities, where staff and students can record videos, such as ANU's new "One Button Studio".  The unit I purchased is an "Eco Solutions 6 Way Master / Slave Powerboard" by Mort Bay, for AU$35.04, but similar units are readily available. If buying on-line check that the unit meets local voltage and safety standards.
