I have a viking quilt designer 11 it has 7 1/2 ' throat now I have a topaz 30 it has a 11" throat I have had the quilt designer since 2006 and it is a work horse I love it. The topaz is new I have only had it maybe 30 days now, so far I like it also. I went with the husqvarna viking we have a dealer close by and I do like the machines.
