For some reason, the SSKs strikes me as another Cherry Red Esc situation. They were rare and highly coveted, until GMK started making them and the market fell out. It was a dark time at Geekhack, because insiders knew about it and cashed out just before the crash. In this case, if Unicomp ever follows through and makes a space saver, it will shake up the market big time. The old PS/2 boards would look a lot less attractive. Perhaps the ISSK will remain expensive due to rarity, but it would probably be affected somehow.
