It's a smooth running, heavy machine (nearly 40 lbs.) and has an interesting stitch architecture: straight stitch machine with a cam assembly, so that zig-zag requires a cam (as well as the other 30 or so designs). The styling reminds me of the model 54 and the bobbin faces forward so it's double needle capable. In back, there's a lever to control the length of the built-in buttonhole stitch separate from the stitch length lever on the front, so they're independently controlled.
I'm just a beginner but for me Kenmore is the perfect brand.
