Jim Kilroy at Barn Owl is terrific. I bought my 500 c/m from him, because he would repair it, too. I drove a couple of hours to his place and we spent the afternoon talking cameras. I've since sent him my Rolleicord for repair and have directed others to him for Rolleiflex repair. Yes, he was trained by David Odess and has his Hasselblad tools. But he's super-handy and talented in construction and home repair, and can do just about anything mechanical.
