How much room do you have?
I got fed up man-handling quilts through my Bernina Activa so I bought a HQ Sweet16 and it is worth every penny.
The Activa is still in use it to put bindings and other quick sewing jobs. My go-to machine for piecing is an old Singer 201; it doesn't have a walking foot but it has such fantastic stitch quality and great for big jobs like soft furnishings.
