Buffy, I can't help with your question but I recently got a meat slicer through freecycle. I placed a wanted ad. It was a long shot but someone responded to me. The machine, a Krups, is old and was very dirty (probably been at the back of a cupboard for about 30 years) but it does work. I would want something more heavy duty if I was doing it frequently but it's good enough for me for now.
Maybe worth you trying the same before you spend your pennies
