Well, as of the moment I have 20. Four of them are 99K's and i use almost all of them. Today son went with our Dd and they go to the thrift stores and I probably will have at least one "new" oldie when he gets home. He and I love these old machines but we have not spent over $20.00 on any one of them. I think it is fun to have more than one machine as one might break down and then there is one more to choose from to sew with.
