No issues with M5 servicing, DAG worked on mine that I acquired on this site. It needed speeds adjusted and he adjusted the meter circuitry for 1.5v. Apparently keh works on them in house, as all sales have a six month warranty. Pretty sure Gus Lazzari works on them too.
There is a recent post here about CLE service by a former Minolta tech.
