This is why I only sew on vintage and antique machines. They are all metal gears and not digital and will sew for ever.
And there isn't much you can't do that you need to do on a vintage machine. Most of those fancy functions and stiches
on the expensive machines you pay so much for you will never use. And that $3000.00 to $9000.00 machine will
cost you a ton to get serviced and fixed every time you take it back to the dealer.
It might be a status thing to have a $5000.00 Bernina but you sure don't need one to quilt.
