I don't have just a ss machine. I have considered buying one but I have the space and use concerns, as well. I have 2 Pfaffs set up all the time and my Featherweight 75 covered to the side. I can grab the Singer and set it up quickly but think I would use it more if I had space to set it up all the time. My Pfaffs are simple machines that basically only do ss and zz but I want to make more clothes which is why I bought the featherweight last year. It is a tough call and only you can decide which machines you will use. Also, look around the house for other areas you could use for storage, like maybe a closet or guess bedroom or do like me and commandeer another unused or underused room.
