Thanks Diving Papaw, I sent an email to Airtech Scuba Services yesterday as well.
I dropped this into the local dive shop for an annual (been 10 years) and they broke the part removing it, ok this is a 20 year old regulator so I get it. What I don't get is yes they completed the annual but just handed me the broken part with no additional information on if the part was available or if they even tried to order it. Not impressed.
Wow. That's pretty awful service. These examples are why too many good LDSs get a bad name.
