It's always nice to have competent work done at the right price and on time!
Had one of my three M lenses 6-bit coded by Leica in N.J. months ago when I bought my M8.2. Their work was fine but it took considerably longer than they indicated it would.
My other two M lenses were just coded by DAG at nearly half the price & appear to me to be equally well done and right on the 3 week time that Don quoted. (shipping added a 4th week for both directions)
Only the 3rd time, over many years, that I've had Don do work for me, but he continues to turn out excellent work at good prices and on time!
Now, c'mon, Leica...announce the M9.2 with a few easily done upgrades including the sapphire LCD glass and I'll ink someone's waiting list.
