Mike does excellent work. I have had him turn barrels around in a matter of days up to and including the last set which I sent in Feb 2017 and got Last week.
Don't know what his situation is but sometimes he is deluged with work. I have called him numerous times and always have gotten him on the phone during normal business hours.
His work is reasonable and very good. so, it boils down to a question of time.
