The market does not seem to appreciate already serviced cameras. To my experience you will not be able to regain the cost of the CLA in selling the camera (if you are interested in a refitted Rolleiflex 3.5A for 590$ send me a PM). As a consequence most cameras which are CLA'd, will remain on the shelf until their status is unknown again (by successors selling the inheritance of a passed away photog for instance). So my advice is to find a camera in decent shape and take into account about 150$ for CLA in considering the price. And do not expect to get your 'investment' back in selling it again.
