I bought this for $37 shipped and I quite am satisfied with it. A shame that it is missing both Controls and F9 and F11, but that thick dye-sub PBT Alps cap set, especially with the blue sub-legends on the numpad, is very nice and hard to come by.
If I could find the pinout I might even try to make it run, I have plenty of good black Alps switches and rust on the plate is really irrelevant.
But the cap set alone is well worth it.
