In 1969 I bought A VIKING 6750. I sewed everything on it, my clothes, husband's suits, etc. I still have it, it still works and I use it whenever the other one is busy.
Last year I bought a Viking designer 1, I like very much. The D1 is not as sturdily built as my old one, but it is good for what I need. I've had Singer Quantum (in my closet) that is no comparison to my Viking. It also lost the ability to embroider some of the designs and would cost a fortune to fix.
My two cents worth. If you can get that machine at a reasonable price, get at least some training on it, also repair for some time, go for it. But, watch your dealer. Some are not as good as others.
