Yesterday at a thrift store I saw a nice, simple Japanese made Universal with zig-zag, no fancy stitches to complicate things. But also no bobbin case. I passed. It's sad when small but very important parts go missing.
I did find some sturdy old tools for $5 and three big storage tubs for $2.50 each to keep my rag yarns in, so that was great. You can never have too many good tools and water-resistant storage options!
