I'm looking at a bernina 950 or tacsew 950, same machines, for zig zag option, repairing horse blankets, I've found some info on the machine but not much, anyone have experience with one, I'm hoping to run tex 70 or 90 thread, some of the machines I've done research on will only do lightweight threads, and thinner materials, I like running servo motor on my machines, I don't need much speed, any info is much appreciated, I did a search on industrial zig zag machines, I did find a list of machines that have zig zag option
