I have a Viking 190 from the same series and it is my go-to machine. Mine is used regularly and will sew anything I throw at it. Take it for a test drive. It was the middle machine in the series and I cannot remember if it has the 1/2 speed feature? I bought a second one from ebay in case the other one dies! If you can get it cheap, do it! My 190 retailed for $800 back in the early 80's.
