I have a few sets of black-on-gray/white/beige/whatever Cherry doubleshots with 1.5x modifiers and 7x spacebars and the off-center Caps Lock in various stages of ABS senescence. I was planning on touching these up by trying that whole retrobright thing at some point, but they still don't look completely awful without it. I can take some pictures if you're interested, or anyone else for that matter.
