@elliottbnewcombjr  Did you read the post?

"Looking for recommendations for a great sounding and bargain cartridge for around $100."

Yes, and you know that I was active in that $100. category earlier in the discussion.

I always imagine others that follow discussions, and that AT150Sa, new open box or less than 10 hours, is a terrific cartridge for a very good price.

And, you never know when an  OP will exceed his budget, having learned this and that recently.
