I have the Pfaff 4.2 that I use for piecing, FMQing , applique, any repairs my grandsons can talk me into. I got this one after using a Pfaff 2134 for several years. It is a good machine, also, but the 4.2 has a larger throat and extra lights. Very happy with both machines. There are so many features I hate to try to list them. I know the 5 has even more features than mine, more "room to grow".
