I own a good deal Of Contax equipment and I love it...an RTSIII and 9 prime lenses obtained over a period of time from Ebay and photo.net as used but like new equipment. I have been highly satisfied with all of these items.
What I was not satisfied with was customer support of Contax USA. Sending them an email to learn something was like sending it to a digital wasteland. On the other hand if is sent a question to Zeiss in germany about their lenses for Contax I got an extremely satisfactory answer, most of the time from someone with a doctorate, and It is by far the best and most interesting manufacturers' website I have visited.
So, I would consider a change in distributorship not likely to be a step backward and I will remain hopeful.
