One more comment on FMQ - So far, my personal favorite for FMQ is the post 1930's 15. I did some on a 301 recently, and the darn tension knob kept blocking my line of sight. I had not expected that. The 15 has the tension in the front and I never felt like I had to move around so I could see what I was doing. It's not a problem to see the needle, but if you are trying to move the fabric to line up with another point that is to the side and behind, visibility is an issue. This isn't a big deal - and not a deal breaker, just my observance for me.
