Computer Christmas has many articles showing you how to do this. There's a how-to for a 320 channel controller. All I need is 8 channel on/off (no dimming), so a simple parallel port relay box is perfect for me. This how-to tells you how to building one. But actually you don't need to build a relay box yourself, there are parallel port relay kits sold online for cheap. You just buy the kit and connect to electric box.
So Here's how to build a Python powered Xmas light controllers for $40(more or less).
1, get a parallel port relay kit for about $32, for example: here or here. You can get it assembled or in module form for a few more bucks. I didn't want to spend much time assembling so I got a module.
2, get electric box and outlets from Homedepot or Loews for total $8. Again I'm lazy so I just got a power strip from Walmart for $4, but it only has 7 outlets, I couldn't find one with 8.
3, Wire the kit to your electric box.
4, Connect to computer and fire up Python (see my previous post).

How much would you charge for an already built powerbar+controller?
You fit the SSR's inside the power strip? I'm trying to do almost the exact same thing, and I'm not quite seeing where you put the SSR's based on the photos. Any help would be greatly appreciated!
Can I use this controller for Christmas lights. http://www.electronics123.com/s.nl/it.A/id.1712/.f
