Other than price, or accessibility, what would be a reason to use a sit down machine without a frame?
Without a frame and a way to move the machine, don't you then have to moose the quilt around the same way I do on my Janome regular DSM?
I think the moosing the quilt around is part of my problems becoming adept at FQM - lack of dexterity with managing quilt under needle properly. I do ok on practice squares but have trouble with a large quilt. I have been looking at the Juki model the original poster is speaking of, and it looks good and gets a lot of recommendations from the Board.
