Well, it’s a “great find” in the sense that otherwise these keycaps can be hard to find at all. It’s not necessarily the fairest price, but people with KingSavers don’t have too many choices.
By the way, anyone who wants to buy one of these and use the keycaps for a KingSaver (presumably with some other Alps switches), I’d love to buy the extra NIB black Alps switches off you (hopefully for pretty cheap, maybe <$30 or something?). (a) I’m going to make some kind of Alps switch tester within the next few months to set off on a tour, and I don’t have any black Alps switches to include, and (b) I’d like to measure some brand new condition black Alps switches on HaaTa’s force gauge and compare with other types of Alps switches.
