You must know that this issue has been covered so many times. Some members here such as, DMs, instructors, or loyal customers, who are on LDSs payroll or get the equivalent discount argue that you have to buy everything to sustain the air refill source. But, in reality, it is so funny because they didnt mention how much they used to get the discount. For example, if they get 20% (it is a common rate) discount for all their purchases, do you believe that LDS does the same thing to the normal customers? Someone who is not on their payroll can argue they also get the same 20%. Oh~~yeah, if then, how much have you spent over there, $3K, 4K, or 5K. And then, you get 20% off? If then, eveyone has to spend that much money to ensure the same treatment. My point is that it is not a fair comparison between the normal customers including myself and other loyal LDS pets.
I think it is a transition period of the scuba market. As you may know, there are many places (including LDS in other places) to do the annual service by mail no matter where you bought. They do the same service or even better in the reasonable price range. Of course, you have to pay the part if the reg. doesnt come with the warranty, but it is not a rip off price. And, you dont need to feel the guilty and study their face. I dont think it is the charitable business that LDS does the annual service. They are doing what you pay for. If your LDS doesnt want to make money, just walk away from them.
Regarding the manufactures warranty, they used to claim their warranty is an international warranty. But, it is mostly a gimmick. There is no guarantee that the authorized dealer anywhere in the world honors the warranty. And, dont be confused the warranty and annual service. The annual service is not the warranty coverage so that the cost of the annual service is case by case. For example, ScubaPro free part is only valid in U.S. I have already verified this with ScubaPro so many times. Some LDSs in other countries asks $160 (reg from authorized dealer) for SP annual service. And, any LDSs in U.S. have a right to refuse the annual service even though you bought the reg. from the authorized dealers. I told you, there is no guarantee! Yeah, they only do the service on what they sold. So, you have a right to walk away from that kind of LDS and not to refer anyone to them.
Some members also contend how you can send your life supporting reg to unknown technician. If then, how long have you known your LDS? How much have you known your LDS technician? Do you actually see their service on your reg.? Some members might see it, but don't get me wrong. It is not a drive through service in BurgerKins. Most divers leave the reg. and get it back later. If some members are really concerned about the service accuracy and quality, they had better service it by themselves. Who can you believe except yourself! Moreover, the service places (such as Air-Tech, Scubatoys, or TDL, etc
.) that I referred do three times or ten times more annual service than your tiny local LDS. They are also LDS, not aliens or foreigners.
Dont worry about air source, it is a supply and demand rule. If there is enough market out there, there are always suppliers. That is the reason why many local dive sites equip the air station.
My 2 cents.
