The seller is silly and set this as 99¢ with a $60 reserve price, and $70 BIN. No one bothers to bid with the reserve price, so it’s gone back on auction like 3-4 times now. But $70 sounds fairly reasonable; I haven’t seen too many split mechanical keyboards cropping up.
The construction on these things is purported to be somewhat flimsy, like other Chicony keyboards, but it has doubleshot keycaps, should be complicated white Alps switches, and the split layout is nice.
Or heck, maybe someone can do something interesting in a custom project with the 4.25u spacebar on the left half.
