Andy, yes I would be interested. My M6 is also working fine, but insurance as far as the winder would be a great thing. Interesting about the flickr link saying KEH would be able to repair the M6 winder. You may want to look into that more and get some sort of verification from KEH before going this route with S.K. Grimes.
At any rate, thanks Andy for looking into this for us M6 users!
