Another one of those "If you read it on the web it must be true". The Logicas and SensorSews were built on the same assembly lines by the same company and with the same parts. IIRC, Necchi had the idea but not the ability to produce them so they partnered with Sears(?) to produce the machines. Differences are cosmetic just like comparable Brothers and Babylocks.
Good going though, to get one on your short list. It is a very cool machine.
