Just to make that list more complete...
The EMG HZ is ceramic
There are a whole bunch of aftermarket options that you are missing:
Nordstrand MM 4.4
Aero MM4 Type 4B
Aero MM4 PHC Type 4B
All of the various Bartolini offerings, although I don't know which, if any, are alnico
All of the various Delano offerings, some of which are alnico
There are a few more that I know I am forgetting
There are more ceramic options, Seymour Duncan makes one and GHS makes one as well.
Let me look into Aero and Bartolini.
