I think you’re wrong about PMC-1, the FR-7f is a much better cartridge, many sellers trying to speculate about FR cartridges trying to sell something that equal to the FR-7f but different, let’s make it clear - there is no other cartridge in FR line (designed by Ikeda-San) that performs as good as the legendary FR-7f and that’s why the FR-7f is much more expensive and absolutely unique in its design (big and heavy monster). I have both the FR-7f and PMC-3 and prefer the FR-7f, but the PMC-3 is very good cartridge too.
Long time ago i’ve come across Jonathan Carr’s post about Fidelity-Research cartridges, to make it short i will put this quote from my notes here (but you can find it on audiogon archive):

From my perspective (that of an active cartridge designer), the closest thing to a non-integrated headshell version of the FR-7 was the PMC-3, but even this remained quite a way off. - J.Carr
