This one feels a lot like an early Apple keyboard (the short version that often sold with the SE) although not quite as "clicky". The switches definitely are not mushy and are rather tactile. I'm not sure where it was made (it doesn't say on the back and I can't find any info for the "AP" manufacturing code before the serial number) but I do know that in other keyboard lines, the keyboards made in Mexico are usually mushiest.
I haven't hooked it up yet--got sidetracked tonight and didn't get around to working on the old Macs--but am waiting to test it. I know these keyboards are supposed to have reliability issues, but for $10, I figured it was worth the gamble and if all else fails, it can become a good summer project.
