I used one for several years. It worked fine for me. I also have a variety of old singers (the all metal ones). I liked the tension on the CS6000I, it was better than my Bernina and easier than the old singers. The stitch is nice too. I gave it to my best friend who likes to make quilt tops but she is nearly blind. This was my choice of all my machines to give her for ease of use. I also bought a new CS6000I for my niece. I think it's a good machine, simple to use, super price and mine came with lots of extra goodies. :-)
