Got mine today and installed them right away. The quality and service of Mark is superb. I love the look of the clear ramps with a few colored LEDs installed. The only LED I added was a color changer in the far back right corner. I will work on some further lighting improvements later, but here's what my installation looks like for now...makes the whole game look bright and colorful.

I like the bright illumination of the clear ramps, but I think Williams would have added some colorful decals to parts of the ramps where the hardware underneath would otherwise show. I therefore made up some decals with the blue stone marble look, the cobble stones, and an orange holographic decal for the ramp by the lions face. I think they turned out okay. I printed them on bright white vinyl decal material and they should be durable. Also they can be removed without difficulty if I ever change my mind. I also added an "Advance Bonus.." decal with a black background instead of the clear labels some other folks in this thread have used. I think the yellow text on a clear ramp would not show up that well. Here's a few pictures including one before the decals were added. PM me if you want to know more.
