I use the x10 lighting control system. While it is not as fancy as the one listed above it works fine for me. Instead of having the scenes set by the system, I use my remote's macro function to program different scenes for me. You can send me a PM if you would like more information but I'll provide some for you here to get you started ...
- I use the IR543 to control the lights (up to 16) which can be found for less than $30
- Radio Shack has a good buy on the above item. They have it for less than $30 and provide you with one lamp module and one appliance module. It is called Home Automation Value Pack and is part # 61-2410.

- Individual wall switches can be found for about $12 each
- Plug in modules vary by piece but are also fairly cheap
Most of this stuff can be found at:

or

(no pictures but if you call them they are very nice people to work with)

Hope this helps and shoot me with a PM if you would like more information about my set-up.
