Just reading many the comments here on the Forum over the years, some guys can't sing the praises loud enough and some guys have had to send their guns back multiple times. Guess it depends on who actually does the work, what day of the week it is, and pure luck. Kind of like any other Manufacturing Company is - nothing more than the sum of their employees.
Guys like Turnbull who actually get their OWN hands dirty do most if not all of the work and so you pay top dollar but are getting the best experienced person in the trade. Employees who work for large corporations are getting paid scale or union wages and to them (at least for the most part) it's a job and they are not worried about their personal reputation too much. Once in a while you do get a skilled, conscientious, ethical worker who does excellent work. Good luck with your 629.
