Bought it for $100. Pretty sure that it is alps based from what I've read, though not standard mount alps, so it's not like the caps would be swappable. Am really hoping for buckling spring, but it doesn't show up on the list of BS Japan boards. Those all seemed to have a part number that starts with 94 rather than 64. Should be a nice addition to the collection even if the keycaps are somewhat shiny.
