Adding in my greetings and my opinion.
I've used vintage machines older than I am for the last 30 years or so. Recently I was gifted with a friend's modern Bernina, mostly because I have vision issues and it is a self threader and my friend is wonderful... but I love the thread cutter so much! I recently worked on a project with partial seams, a breeze with the thread cutter. And as an added benefit I could tell that I had a lot less thread stuck on me afterwards instead of looking like a walking thread ball.
I also like the knee lift bar to raise the foot up and down, my friend never used it but I have already adapted to where all of this is on automatic.
