Since I have gotten 'into' quilting I don't do much machine embroidering, however I own a Viking D-1 that served me well but is now out of touch as it used floppy disks and not compatable with my new computer. I still love it for the wonderful deco stitches it does. I use it for deco machine quilting on small quilts. Viking is a wonderful product.
I have since bought a Pfaff embroidery machine which is very nice also. I bought it for the walking foot that is built in.
It too is a wonderful machine.
I know a lady that does beautiful embroideries on a Pfaff machine for our church quilt ministry...I don't know what machine it is but it accomodates a large hoop.
My dealer told me that Viking and Pfaff have merged so they are one company now.
It ultimately will be your choice. Good luck..So many great machines for us to enjoy.
