I have the Viking you're asking about and I'm very happy with it. I don't use the fancy lettering or stitiches (just haven't learned how yet). I really like the fabric thickness sensor feature-it sews over anything. The only thing I wish was different is the space under the arm--is that the "harp" area? I do wish that was larger for easier quilting. If you go to the HusqvarnaViking website they do a nice comparison of their machines but remember they're selling their machines. If you have access to other brands, I agree with the others-try as many as you can before you make your choice. I would choose the Sapphire again even if I had other choices. Of course if I could afford the new Viking, I'd get that but I'd rather buy a new car (very expensive!!) Good luck and enjoy the hunt.
Peace-Jan
