I also have a "Siig MiniKey" or something acquired new in box from a cheap/used electronics reseller, with Alps switches.. for $5.
Actually my friend bought it on a whim. They had a huge crate of them there, all new in their boxes, recovered from a sell-off from some corporate warehouse or something. I got it from him later, when I saw it, and I could instantly tell it had Alps switches in it. He said it was only $5 so we ran back to the place immediately -- but someone had already scooped up the entire crate of them. The place selling them had no clue they were worth a bunch of money. Otherwise, I would have bought all of them myself. I guess someone else had the same idea as me.
