Steve here... I too have seven working RL1000's. One of them is as new, with the boxes. Likes others have said, parts are tough to get, I make what I need and a few years back I was still buying shell plates and some other parts from Dillon. Gary K. at Dillon was a wealth of knowledge and could very easily look up parts. He retired years back.
I am very lucky to have the machines I do, they are works of art and run well.
