I've had Vikings for 34 years!!! Loved the 1977 model 6460 that is a real work horse. I bought a used Designer 1 about 5 years ago which I never did like or get used to. Sold it this spring & bought a Viking Emerald 203 which I really like. For some this may seem like a step down, but for me it was a vast improvement!!!!!!
I think the people who have said to test drive different models have the right idea. Also right idea about the new Singers not being too good. But please don't close your mind to another Viking just because you had one bad experience. Good luck with your shopping!!!!
