That's the same thing I went through here in Macon. I dropped my machine off and they were going to charge me $25.00 to have the repair guy take the embroidery unit with him. That wouldn't have been applied to any service work, it was just for him taking the unit with the machine.
I brought it back home and took it to the dealer I bought it from in Kentucky when we went up there for a visit. They never charge for the service man to take the embroidery unit.
