Yes,the new keyset is SA profile, the standard set was OEM (I just learned about those things). I don't see much difference to be honest. It's a brown switch Filco. I'm contemplating buying O-Rings to make the key bottom out smoother and to decrease the keys sound, not sure yet. 40USD a piece is indeed pricey...for comparison, the Filco double shot ABS is 51€/47£.
