Yes! For much less than I paid too. The key switch in the upper left is broken. I may pick it up myself if someone doesn't beat me to it. Or I can proxy it for a modest fee.
Yes. It's a completely smooth linear switch. Since it is a non-contact mechanism the only thing you feel is the spring. Somewhat annoyingly, the keys are rather heavy, and the Enter has an extra-heavy spring. This can all be fixed of course.
Hall Effect switches are rated to last longer than just about anything else. I wonder, was the COMPUDENT RAFI board that just sold, also Hall Effect?
