You could say to the neighbor, "Wow, that was a lovely machine! Unfortunately as I was looking at it, it seems it needs some work that I can't do (because of money, bad wrists, whatever) and I don't know who I could ask to help with it. I hate to see it sit unused, so would you mind if I ask some of my friends if they might want it? They might be able to fix it up like new, imagine that!" I've used a variant of this on things like computer towers (I gutted the innards, rebuilt it, and sold it on)
