I have two what are called now vintage Viking machines - both are from the mid '70's. I have had one since it was new and the other I purchased a few years ago from a friend who could no longer sew. I use that at our winter home. I have loved those machines. I recently purchased a new quilting sewing machine - one with a large harp area. I did not purchase a Viking not because I wasn't happy with a Viking but I wasn't happy with the dealership near our summer home and there isn't a Viking dealer close to my winter home. I can't answer your question on the particular Viking machine you are asking about but I am pleased with my Janome 8900qcp. I don't know what other machines you are looking at but for me I need to feel comfortable with the dealership as well as the machine.
Good luck in your shopping. It is almost like shopping for a car with the comparison and price negotiation involved.
