Relay board for the RPi

Hello,

I got bored of my boiler and central heating timer controller and decided to build one controlled by my RPi. My plan is to then develop a simple Android app so that we can control the boiler from anywhere.

To switch the high current and voltage, I will need a relay board. Can any of your point me in the direction of a cheap one that can integrate with the RPi? Or can you think of an alternative solution?

Thank you!

You might want to have a look at this thread http://www.raspberrypi.org/phpBB3/viewtopic.php?f=37&t=15281. I've already developed both a java app to do the switching (for stability) and a web frontend to control it from my PC or phone. All the functionality is exposed via a simple JSON interface so you could build an app for it pretty easily but I find the web browser to be fine.
