Local to me is a used but very decent looking 3pt middle buster. Asking $100 o.b.o Not sure what I would do with it yet, but should I just offer him $80 and see if he bites?
They also are great for digging potatoes, and can be bolted on to many 3 pth implements you may decide to make.
I just looked them up... yikes! They've doubled in price since I bought mine about 16 years ago.
