vintage zig zag machine

[jk1066]

I have a very nice modern janome that does several fancy stiches and of course zig zag. I have some heavy fabric that should be sewn with a zig zag - think sail material from a boat. I don't want to ruin my modern machine so I'm looking to buy a second hand  more robust vintage one - with a powerful motor and does zig zag. Any ideas of what machine would be good?

If you want a really powerful motor you are looking at an industrial machine. 

My daughter has a Singer U20 which she bought 35 years ago and still uses regularly in her curtain making business.  Variable width zig-zag but nothing else fancy on it though the motor is a huge beast and the whole thing is a two strong person lift.

In lockdown I gifted my 1970s Frister and Rossman but I reckon that would be suitable. Trawl the charity shops for similar machines.
They were heavy beasts to lift and only had straight stitch or zig zag but they were reliable.
