I have a 101 from 1929. It is straight stitch only, sews a beautiful stitch! Mine just stopped working, I am pretty sure it is a wiring problem. Not sure if I will fix it or not as I have too many machines!
I have a 201 also. It is very heavy, straight stitch only, quiet and sews through anything with a beautiful stitch! The feed dogs drop and you can FMQ on the 201.
