Sewing Machine Expert Advice, please! Sewing Machines Parts and Sales in Los Angeles

I have 3 sewing machines and I need to figure out which one to keep. I want the one that will be best suited in the long run. (Maybe better quality, reliable, heavy duty, etc)

1. Singer Model 1120
2. Singer Model 603E
3. Brother VX-940

I’m not a professional obviously. I’m an art major and I want to start incorporating a sewing machine. Ideally, the one that can take the heaviest material out of the bunch would be nice.

Singer number 1 is the newest. Seemingly “cheapest” quality?

Singer number 2, I know nothing.

The Brother model has a ton of stitch settings. It’s from the late 80s I think.
