Others have mentioned the Belkin WeMo, which seems to be the best solution for anyone who doesn't want to mess with circuits (though I have no experience with, so can't comment). Does anyone know if it is available in a 220v format?

But if you do mess around with RasPis or Arduinos for that, I can't stress how useful the PowerSwitchTail is http://www.powerswitchtail.com/Pages/default.aspx - you give it a low power signal, and it switches a high power one. They have a 220v version as well.

It's sold in New Zealand where I am, and we are on 240v.

Thanks a lot for the link. I've been idly pondering a couple of projects that would involve switching mains power with a microcontroller, but didn't encounter anything like that at a price that made me want to consider it. You may have saved me from a fiery doom.
