Technics SL 1100A & Sl 1210MK2 ToneArm Upgrades


I have both the Technics SL 1100A & Sl 1210MK2 and was wondering what would be the best route to take regarding ToneArm Upgrades? I can spend anywhere from 300 to 500 on each arm with mounting plates , rewire etc .
Thanks in Advance

Thanks, Johnny. Cost be damned. I'm going for the $1.47 stuff. Appreciate it.

A Rega or Origin LIve tone arm can be used with this adapter:

It is not an uncommon practice to use this arm board to mount a Rega or Origin tonearm on a SL-1200 TT. Don't know about a 1100a. Does it have a removeable arm? I'd contact the arm adapter manufacturer.
hi everybody thanks for all your kind and helpful responses
regarding the 1100A is is the the stock EPA110 arm thanks
