I have the opportunity to buy a lightly used Sweet 16 for $2500. Will this machine handle queen size (king size?) quilts easily? I've been using my Bernina, but find I can't quilt large quilts so I end up doing quilting as you go which I don't want to have to do. Will the Sweet 16 solve this problem? Is this a good price if I trust the seller (I do)? What would be your main hesitations?
