Purchased 4 new Light-O-Rama controllers (PC-CTB16 Ready-To-Go) in the 2011 March madness sale. You can get the kit where you solder the board together, but I'm horrible at soldering. You can also get a board partially assembled, but I went for the completely assembled ready-to-go controller.
In order to use the board you just have to set the Controller ID using the hardware utility that comes with the Light-O-Rama Software Suite S2. It's an easy job and only takes a couple of minutes.
The top video shows the whole process. The 2nd video gives a better view of the software.
