I asked CO friend, and he says:
Secondary legends are pad-printed, but in FOUR different colors---red, purple, green, blue. Pretty cool.
I don't think I've ever seen a KB with more than two 2ndary colours (though you guys prob. have). If they'd accept, say, $60, seems like a pretty good deal to me for a rare NIB MK!
If you're concerned about wearing out pad-printing, remember, dirt is abrasive—so it's always a good idea to wash your hands before you sit down to type. Seems like a pretty civilized habit anyway, doesn't it? Typing with clean hands, I have yet to wear off
any pad-printing. I've often thought of starting a topic on the idea here, but I figured I'd just get ridiculed. :?|
