For your Craigslist consideration today here's a used Juki serger. Model M0-104, for $140 cash or Best Offer, FOB Pomeroy WA.
Coming out of short term storage, with pedal, printed owner's manuals, and as you see it.
Plug it in, press the pedal, and it whirs away, like the technical little marvel it is.
Open the front door for the threading diagram, swing open the tray under the deck, and find all the tools and bits and pieces.
Probably would benefit from a cleaning and fresh oiling.
Time to send this overlock stitch machine on to a better home.
