YES: DAG & Sherry.

And I'll mention here how much I miss Steve Grimes.

( he did a sweet M3 for me back in ... well, never mind. )

AND, if it isn't too far afield, for vintage Contax gear, Henry Scherer.

Avoid anybody that puts his thumb on the viewfinder and says, " Gosh, I've always wanted to work on one of those ! "
