I have only 5. I did give one to a friend whose machine was on it's last legs and sold a couple of others. From now on I am keeping them all. I am looking for a serger (never had one before), I think it will come in handy for making housecoats and tote bags. I looked at the Janome 12000 on Friday and am really thinking about getting one. I love the big hoops it has. We'll see what happens.
