I've used Plexi painted black on my first two projects and I was surprised at how good it looks when done right. My first one I used black vinyl paint that didn't cover well. It looked fine in the end, but took many coats. As far as Lexan scratching easily... I've actually heard the opposite, that Plexi scratches more easily. I'm just starting a micro-mini weecade style tabletop that I've decided to try Lexan on, so I can't say for sure yet. Although you have to be careful while working with the Plexi, once it's installed it's not too big of a problem with scratching. At least in my experience.
