I have a C's shifter listed on the forum for $375 shipped, a bit cheaper than the JP3 unit these days.

Good luck with the search. The Mazdaspeed and JP3 short shifters do come up occasionally, but FD-specific parts are getting harder to find in good condition. You might also want to check if any rebuilt OEM units with upgraded bushings are available, as they can sometimes feel nearly as good while being easier to source.
