For what it's worth, I sent a message to Mr. Van Dijk last week, and received a reply in a few hours. We've exchanged several emails since then, and I've just ordered a hard-to-get part from him. (Of course, he did have the part I needed.) Just another experience.
Try Star Quality, which I'm sure is in this site's list of parts sources.
