I have a Babylock Espire and love it. When I took my free lesson, another lady was there with a Brother that was almost identical. I asked if they were made by Babylock. She told me that Babylock did not make Brother and that Brother did not make Babylock, but they used the same manufacturing plant and that's why the machines look similiar. They give them the specs and they build it for them.
I guess it would be like two soda plants using the same bottling company.
