Likethedog, I can't tell you anything about the newer Singers (mine are vintage) but I do have the Brother CS6000i and it is a great little machine for doing home projects. I have it set down into the table and have no problems with it moving on me because of that. I also use it for anything needing fancy stitches. I wanted something with a bigger throat so I could learn to FMQ so I bought the Brother 1500s, which is what I use for everything that just needs a straight stitch.
They both have their place and I use and enjoy them both! The CS6000i is a good little inexpensive, all purpose machine if that's what you're looking for. I hope this helps.....
