My Elna SU Air Electronic is the machine I have had the longest. It was purchased it in the early 1980's, OMG at least 32 years. It was the "cat's meow" then. It took me a long time to pay off that sewing machine. I actually don't remember what she cost, but was quite spendy for that time. I traded in a old green Elna, not the Grasshopper, on the SU but I wish I had kept that green machine. Now I am looking for one to add to the collection.
