When LED ColorDMDs were still listed on Ebay, I used a discount and picked one up cheap. SC was the first machine I thought of putting it in, especially since the LCD doesn't fit anyways. But color didn't impress me as much as I thought it would. So I moved it to my Star Trek and was much happier with it in there. I find some games it doesn't make much difference to me, and others it's much more impactful. I'm content to leave my SC with the plasma.

Of course, if you get them for all your machines, what does it matter. I'm just not that extravagant.
