I came across one today. It has Monterrey dome with sliders, one of the best rubber domes. Very tactile. The best thing about this keyboard though is the double shot alps keycaps, which was why I even grabbed it, but I could totally type on it and not have a single complaint.
A big bonus is the keycaps were designed for a proper alps keyboard, with the proper stabilizer mounts, even though the keyboard doesn't even use most of them. Downside is the bigass enter though.
