All these shells are aluminum, the main difference is weight and wires. Zupreme made by Jelco. Some other headshells made of magnesium, titanium, wood… One of the cheapest and best new headshells is AT Technihard series (fully adjustable).
There are so many great headshells made in the 70s/80s, my favorite are AudioCraft headshells, they made heavyweight too. Grace carbon-fiber headshells (HS-6) and Grace HS-8 are amazing. Ikeda headshells with overhang adjustment are very nice. Stax made lightweight headshell with azimuth/overhang adjustment. Denon made some nice headshells, Sony made nice headshells. Pioneer made carbon shell. This is the one from Kenwood for example. Technics made Boron-Titanium headshell for the EPA-100 mkII tonearm (unfortunately missed on my tonearm). There are many others. Basically, every manufacturer made their own headshells or ordered them from other manufacturers.
