I'd imagine you could do the rope lights for far less than $100. That's more than what I spent for the entire RGB LED setup including the power supply and controller. It looks like zenscope found a source for the whole setup around $50 too. That's not bad for cuttable, controllable LED lights. Of course outside of having company over, mine usually stay on "white" at the dimmest setting. At the end of the day I think any sort of bias lighting will get the job done of adding a really great look to the screen and reducing eye strain.
