Awap,
You may be correct under your circumstances... The shop I deal with charges $20.00 per stage, nothing additional for servicing the hoses and accesories... They do charge for computer batteries if needed. Service on a standard set is 60.00. So, if you are paying 100 (OUCH!). and I really feel for Pjones paying 130.00. So, no... I am not a "Shyster", and I haven't "Drank the Koolaid". I just seem to be dealing with a better shop than you from a customer service and price standpoint... I can bring my gear in anytime and they will look it over for free... They don't worry about nickel and diming me for every little o-ring. Additionally, for me, there is immense value in the immediate turnaround I get by not having to have everything sent out.
I use my regs quite a bit more than most people, so for me servicing at least annually gives me the confidence in the equipment that I desire. I can typically start to see a degradation in the ease of breathing on mine after about 100 dives and they are great regs. My regs get a lot more use than the dives I officially count. Around 90-100 dives per year for my own enjoyment, and that many again If I count all the times I am in the water helping teach, co-teach, or asist with classes.
My situation, then may not be typical, but I don't think it is totally unique, either. I didn't realize all your dive shops were so horrible. Of course it makes one wonder if you aren't being assessed a PIA fee. Just kidding. I geuss it depends on the shop, their overhead, cost of living in their area, etc. Hope you guys can find better pricing and service in the future.
If I had really drank the Koolaid, I'd be buying a whole lot more gear that I don't need. I don't really think my shop offers Koolaid... They all seem to drink budweiser, just after the shop closes.
I really just want everyone to have as good a relationship with their LDS as I have with mine. Some people look at their LDS from a business only approach... If you can really become friends with your LDS, then you might find that freinds watch out for each other... But that is a whole different topic dealing with individual personalities and what each wants from diving and the relationships stemming from such a great activity.
