I have several Berninas, from older mechanicals to newer computerized models, and I only bought 2 new, and one of those was on closeout. One used machine was from a Bernina dealer, with a one-year warranty and classes (which I never took). The others were from private sellers. So use all appropriate caution, but go for it! Super price if all is legit and in good working order.
I've been away from QB for quite some time, hugs to my pals here
hope everyone is well.
