My mom *just* gave me a magnetic guide
@Cheshirepat ! She bought one, and it came with an extra. She was kind enough to give it to me. Thanks for giving me things to look for - I asked as many questions as I knew, but I will definitely check about the bobbin case. Just a few Google searches have shown me how much people love these machines - and it's certainly less than I would pay for a Juki.
