Hi mdelcour. I didn't get a chance to welcome you to the forums. I use Light-O-Rama and love it. I have looked pretty regularly for used systems. I hardly ever see it at a price low enough that makes it a great deal in comparison to buying new with full warranty and support from LOR.
You might consider getting one of the kits they make if you can solder. I'm thinking about going that route to add to my display. I'm not an electronics guy but I have a son-in-law who is and will do the assembly for me.
If you have some pictures of your display, you can post them in your photo album. I'd love to see some.
