I have the Brother CS6000i that I bought for about $150 from Target online (was actually cheaper than Amazon at the time). I got it so the feet would be interchangeable with my larger Brother. The feet are, but the bobbins are not. My large machine is from 2002 so that could be why. The CS6000i has been a great machine for taking to classes. The only thing I miss from the larger machine is the auto-threadcutter.
