Not sure if this is the right place (so mods, move this thread if it's wrong), but there seems to have been an influx of people from the Columbia area so it's relevant only to them.

I was at the His House thrift store in Lexington on #1 across from Barnyard Flea Market and they have sewing machines (thread injectors) there at $5 a pop. I almost scooped a few up, but didn't have time. There's one Singer in particular there that looks REALLY good.
