I'm also currently looking into the Edge 4.3 Touch screen Insight CTS. I want just the display, not the kit that actually allows 3 different tunes. I want to be able to monitor the various parameters of my setup without having 1 million gauges in the dash. And yes....I think if properly mounted it would look killer. I was thinking of something similar to the new Chevy trucks where it's an info panel mounted in the center with the tach/speedo mounted on each side.
