I just found the answer to one of my own question...

Still not sure about that LCD though...
I too would be interested in the actual costs of repairs from different owners. It would help me make a decision as to whether I should send it in for repair. My camera's mirror hasn't failed over these several years, so maybe I'll just wait it out until the Mk2's drop in price.
