@rauliruegas I would be absolutely shocked if you can provide evidence that SME V at some point had a knife edge bearing. This is completely false. But I'll eat my words if proven true.
Good news, but the old 407/23 is that good?

Btw the "23" is the angle. The wrong one was Saec 308 models, and probably 317. 
Earlier SME tonearms were known for the knife-edge bearing.  It was one of their advertising points.  If the SME V does not incorporate a knife-edge bearing, then I stand corrected.  Whether it does or does not is irrelevant to me.  Is it shameful to use a knife-edge bearing?  If so, I never knew that.
Should make the SAEC 407 ( i believe its a 23 as I can use its alignment template) worth a few more bucks. I am getting ready to pull it off and mount a Technics EPA 250.
