I just looked at a 830 at my Viking store it was more than $899 so that seems like a good price. I have a D1, a Emerald and a Viking Serger and have never had one in the shop to be fixed, just occasional service. The extra throat size would be great. I do all my own free motion quilting on my D1 and the machine makes it easy. I love the pressor foot raising without having to lift it, makes it really easy.
