My 401 is the one I have set up in a cabinet for everyday sewing. The 500 series would be just as good and some offer more stitches if that is what you need. The 301 is my carry around (16 lbs) with its fold down handle on the top of the body. A featherweight (221) is another great choice to take to classes etc. The 201 is a real workhorse, but very heavy. Fine set up in a cabinet and you would love that as well. If I could only have one, I would be in real trouble!
