I agree with HettyB. Although I don't have the sweet 16, I have a platinum 16. Pretty much same machine put out by Huskqvarna/viking. Fortunately I don't have to ship mine off to be serviced. I bought the sure foot for the sweet 16 and installed on the machine to do ruler work. Pricey but worth it. My biggest issue is tension although I am getting that worked out. My machine came with the true stitch, but really don't use it that much. Purchased this machine as it was on sale and also came with the true stitch regulator. Also have the table overlay.
