My Viking machine is about 15 yrs old but I love it. I have not had one second's worth of trouble with it and rarely have it serviced. It is computerized but does not do embroidery (didn't want that feature) but it does have some embroidery stitches and an alphabet. If I spent more time with the machine I could probably master those, lol.
On the rare occasions I have had it serviced it's been at the same shop where I purchased the machine. The service guy there is great.
