I too have a favorite. It's my 221. I do have others that I just purchased. One of them is a 99K. I haven't even tried to sew on the other 2. I am going on a trip this week and taking my fav. When I get back, I will have to try the other 2 machines.
Just sit back relax and take a couple of deep breaths. Do something else you enjoy and before you know it, your baby will be home. She does need some down time too, even it is to get repaired!
