This is how my LDS/ESDS treated me today - I really felt cared for. (Not a Atomic Reg)
My LDS is not acting like it's trying to eat me up to survive. I took my backup reg in and my older Suunto Vytec/backup computer with a discolored battery cover - and do you know what my LDS tech charged me today? He cleaned up my Vytec, put a new battery cover and battery/O ring, and pressure tested it (112 ft it reads). He also went through my reg set - and said it all looked good - nothing need to be replaced (it has been sitting for a number of years with only a few dives). For all this work, Ed/Tech/my LDS only charged me $35.00!!!! And then we visited about computers and my reg manufacturer (Sherwood - as compared to some others inner workings) for another 20 minutes. And mind you, this is a busy LDS (medium sized w/4 full time over 40 year old instructors & bunch of turnover kiddies/college/DMs), but I dropped off this reg early this morning (before officially opened) and it was done when I got there at 4:30. (Oh, and they didn't say "BOO" about my wearing a sweatshirt from another diveshop where I get air on the Coast)
It is very obvious why this second generation LDS continues to keep it's doors open. I truly felt like most of ESDS's customers - special.
My answer to you about how much you paid is this.
--- Is your LDS there when you need them?
--- Are they about themselves, and not their customers? (Obviously we all must make a living)
--- Do you usually feel ripped off by them?
--- When you think of their expertise and the time they spent on you reg - how does their hour wage look - especially with their overhead?
The answers to these questions will tell you if you paid too much.
