I picked this setup off ebay the other day and installed it tonight after work. It's extremely simple to put together. If you can plug in a lamp, you can handle this. It has several features for switching between colors. There is a wheel to dial in what you want and lock it in and there are two scroll modes. One switches between colors and the other is a fade mode. I snapped a few cell pics as it faded between colors to give you an idea of what it looked like. I've got about $60 in it and while I wish it was slightly brighter, overall I'm really happy with it. There are 4 led strips you can install just about anywhere you can fit them. I have two strips above the highest shelf and the other two are actually attached to the bottom of the first shelf. Here are the pics.
