I sure wish I had found out about the prism foam damage issue before I bought my camera. I did find some info buried in a thread about the Mamiya M645 foam damage issue but it took a lot of searching. Maybe this thread will alert prospective purchasers as to what questions to ask the sellers. I don't know if anyone has found a reasonable place to re-coat the prisms. I did find someone who coats telescope mirrors but at $50 it probably isn't going to happen.
