Available from TMB Baking, founded by Michel Suas (who also founded SFBI).
I own this machine—it was sold under a different brand back then. It’s really powerful, but it doesn’t have a dough breaker, which I wish it did. Honestly, I wouldn’t have paid full price if other spiral mixers with a dough breaker had been available at the time. That said, at $700, it’s worth a look.
