I have a Technics SL-1210MKII and I used a AT-150MLX which is out of production but still available on the web. The 150 was a great match with my older stock arm. I changed out the arm to a Jelco SA750 a few years ago and it has remains my go to cartridge. Search the forums there are tons of positive comments.
Note. I have used a Denon DL-103 with the stock arm of the 1210 but used a 11 gram head shell not the 7 gram technics one. It was not the best match but worked ok. After changing the arm to the Jelco it came to life. It will work on the stock arm but not to it's full potential.
