I have a viking topaz 40 which I have used for a bit now. I actually haven't embroidered with it yet but the reason I bought it is that my old Viking D1 finally stopped working. I had done a ton of embroidery on the D1 for many years and the shop told me the Topaz 40 was the closest to my old D1 plus it has even more features. I do think the Topaz 50 would be great. It also has a bigger harp space then the topaz 40 so you will be able to do larger embroideries and if you do quilting it will be good for that too.
