I owned a Viling Designer I and had many, many problems with it. I finally traded it in for a Baby Lock when I was told it would cost qver $300.00 to repair it. Even though it was an embroidery machine I hated to embroider on it. It was very unpredictable. It would be sewing great and then it would mess up and I would have to start all over. I had it back many times for repairs. Another problem I had with Viking was the software you could purchase to do your own designs or edit other designs. It was very expensive and it was not updated after a couple of years. You were expected to buy the next version for hundreds of dollars more.
I love my Baby Lock and enjoy embroidering on it.
