Oh I can so relate! When I traded in (okay I got $50 for it and it didn't work that well) my last machine, my LQS had to give me a tissue. DH thought I'd finally lost it but I sat there and remembered the baby clothes, the little dresses, the teddy bears and the moves all over the world with that machine. I felt like I was losing my best friend.
The good news is your new machine will hopefully become a good friend too!!!
