I have my S16 for a couple of years now, and I love it! My FMQ has improved significantly. More importantly it is so much easier to quilt! There are occasional complaints, generally about setting tension. I had no problem with it, but I have used vintage sewing machines and professional multineedle embroidery machines so adjusting tension was not a problem for me. There is a good Yahoo group with very helpful folks.
Note the Babylock Tiara is built by Handiquilter for Babylock. They are the same machine. There are also other sit down machines coming out now so choose one based on good support with your local dealer.
