As Fred J says below, some of the Sony arms are worthwhile. The Sony PUA-7 was sold separately, as were the earlier PUA-237 and PUA-286, and the PUA-1500 and -1600. The higher the number the more likely one could find one. The PUA-9 was sold separately but not in any great quantity I don't think. One does come across them but once in a blue moon.
The EPA-100 and EPA-100Mk2 arms which came on the SP-10Mk2 and SP-10Mk3 in their SL-1000Mk2 and SL-1000Mk3 implementations are great. There weren't that many Mk2s made I don't think but the EPA-100 can be found reasonably easily.
Some of the Denon arms are quite alright - the DA-308 long arm, DA-309 regular arm, and the Da-401 light arm, as are the Victor arms which were sold on the earlier versions of those tables, the UA-7045 and the UA-7082 long arm. I think the Victor arms are under-appreciated.
Pioneer's mid-70s efforts had some great arms which were also sold separately. Muzikmike, who seems to hold up the walls of this asylum, can attest to those arms. On the later tables, only the Exclusive P3's arm the EA-3 was sold separately with any acclaim (though it is possible the EA-10 arm was also sold separately, I don't have the catalogs). The EA-3 is a fantastic arm.
In conclusion, I would generally say that they are excellent arms for the money they command. The EA-3 is the best of those arms, I think easily competing with modern arms, but it is not cheap if you find it separately.
Most of the motors mentioned in my earlier post on high-end DDs are available separately (i.e. without arm or plinth), or with their original plinths but without arm. One could easily change arms for most of them. Out of all of the original manufacturer plinths, the later high-end Denon plinths are good and the Victor plinths are good. One wants to change the footers if possible but that is easy.
The super-high-end tables like the Denon DP-100, Exclusive P3, Sony PS-X9, and Kenwood L07D are basically stuck in their plinth, and in all but the case of the DP-100, also stuck with their arms (though the P3 could be adapted to use other arms with 270mm mounting distance). This is not a bad thing in any of those cases. Of those, only the Denon DP-100 (and only some models) were specifically meant to have arm choice be the buyer's choice.
As to the clamp ring accessory, the Kenwood came with that option, and the power supply has a switch so that the settings regarding weight/inertia, and required torque are adjusted for the difference. Other DD tables would not accept that easily. The key is that the speed-correction circuitry is something of a closed loop, 'tuned' to match the torque of the motor, the timing of observation of speed, and the mass/inertia to which it is applying its force. Add significant inertia to the loop (through an outer ring, or a really heavy platter mat) and everything could get out of whack. In general, I would avoid adding too much weight.
