I have ran across a potential good deal locally for a couple of sewing machines. The models are a Singer Stylist 457 and a Singer Stylist 778 both older machines. Does anyone know anything about these two machines? Would they be capable of sewing webbing and most gear making? They seem to be in good working order although Id really need to check them out personally to be sure. But, for $20 (not sure if this is for each or the pair)....should I just go for it?
