The Kenmore machine in the video was probably made for Sears by Janome. That partnership was in place for quite a few years. However, Sears no longer sells Kenmore sewing machines, although it does still sell parts for them.
Tuesday Morning sells a lot of closeouts, so most likely this Kenmore machine is one of a batch of closeout machines. If the price is right, it could be a reasonable machine for a beginner.
