By the time you get your baby back, you'll be used to 'making do' on your other machine. I do have my favorites as well. I need to spend more time using my vintage machines, but I always go to my Juki to do pretty much everything. I have it set up in my main sewing space and have all colors of bobbins loaded for it, etc.
I bought a Singer 301 at an estate sale about a month ago, and haven't even sewn on it yet. Shame on me!
