Hmm... I can't seem to find any chrome ones on-line right now. I did find some info that Napoleon was out of stock of the chrome ones last Summer, but I'd think that would be taken care of by now.
As far as the finish on the black ones is concerned, I have a feeling that the people who said the finish doesn't hold up well were referring to the cheaper brands. The Napoleon mirrors often get a bad rap because they get lumped in with the inferior, but similar looking brands.
