No defense intended, Alan, just a testimonial. Mark still works a day job (as of a year ago anyway), and repairs indicators and other tools evenings and weekends. His fame has caused his return time to grow longer, though he will take "rush" jobs, ask. If you are not in any hurry, tell Mark so, but be ready to wait a couple months for them to be completed and returned. Note that Mark works on all kinds of tools, ask if you have stuff besides indicators that need repair.Bob, no need to defend him. I am not attacking him. I just wanted to understand the inference that he is "authorized" when another service is not. Emilio cleared that up.
Briefly looking into this in the last couple of days, I have found much positive "forum" press about Mark on other forums and Facebook. He has a dedicated following and that is impressive.
He does not have a website nor does he have a published price list. He does respond to email via the address that Emilio was kind enough to post.
I have sent at least six indicators of my own and a couple dozen that belonged to others to MR Tool Repair and have been completely satisfied with his work. I do not care if he is not authorized, he knows how to fix them so they work well, and they keep on working, no early failures.
