If I wanted a sit down this would be it. Only 43k stitches? good grief it's not even broke in yet.
You don't say how old the machine is but if she just traded up I bet it's not that old. Handi Quilter is good about warranties. If the machine is less than a year old they might transfer(start over) the full warranty. They did it when I bought my Avante although I bought a demo machine from a dealer.
