I have an opportunity to buy this Viking "Rose 605" model machine for $250.00 from a friend who is a professional sewer. It is in excellent shape, complete with all parts and instructions. Am I getting a reasonable deal? Anyone know how much this machine went for originally and when it came on market? (Am wanting to transition up from my 1950s-vintage metal-cased Viking and do not need all the latest bells and whistles that are available on the latest, greatest models.)
