That might be high. The 14U64, used, was blue booked at $215.50 in 1988. I believe I sold the last, used, 14U32 for about $150 back in the 80's. But, if the machine has all the orginial assessories and the owner's manual and is in great condidtion, it could still be a good deal. A new serger can run $300 for a basic one at a discount store (Wallmart, Sears, JoAnns, etc.) or $400-500 at a dealer's. Will they teach you how to thread and sew one it? Can you take it for a test sew in the store to see if you like it? That can be just as important as the price.
