I know @mijostyn does not like removable headshell’s, but I prefer them as I can swap out easily for my mono cart when need be. I bought a Jelco 850 MKII from a recommendation by @noromance here on agon for my Sapphire. The 850 and 950 Jelco’s are much different than the earlier 750/550’s, etc. as they have a balanced ‘knife edge’ bearing. I like mine, and it was about $1,400 new. But, good luck finding an 850 or 950 now. Personally, I would search out a 850/950 before considering a 550/750/etc. arm.
Alternatively, in that price range, there are now better and more available arms, like the Origin Live series, or the others @mijostyn mentioned.
