I'd like to give my 2c.
I'm somewhat disappointed with my LDS. I'm not sure really why I feel this way. I brought my reg to the shop and they said they'd have it done by next week. I guess this was the first blow. I can take my reg apart and put it back together in 10 minutes. Stick an IP gauge and other hoses, attatch it to an air source, then test and adjust. Shouldn't take more than 30 minutes tops! I mean, they won't even have to clean it anymore, since I cleaned it all up myself!
Then I asked for an estimate. The proprietress gave me a figure that was double to what I estimated by calling the shop the day before. She said that they weren't sure what parts to change, and if I wanted, they could open it to check, but that would cost me the full service charge just to get an estimate. Then I started to tell her that I already inspected the parts (with a magnifying glass, and an otoscope for the internal parts) and everything else was okay, except for the o-rings, the HP seat, filter, circlip, and diaphragm. I started to tell her about the problems I encountered with it, but at this point, she starts talking to another customer and acts as if I no longer existed.
But what could I do? They couldn't just sell me the parts. Against store policy.
Okay, now I can acknowledge that they can get busy - hence the delay, and I know that service isn;t just a matter of throwing in a parts kit, but for goodness sake, they didn't need to do the whole "are you still here?" schtick. Spend or get out. Well, at this point, for me, it wasn't about the money, but the quality of treatment I was receiving. Its enough to make me want to change LDSs.
I'm going to stock up on parts and start doing my own reg maintenance.
