Why would you think that LP could NOT obtain work from the original manufacture, or an authorized dealer? Who do you think that LP is purchasing from if NOT an authorized dealer? According to sources on this board in the manufacturing lines, LP get's their gear from none other than Authorized dealers. It would follow that they have a VERY good realationship with not just one, but MANY MANY such dealers.
I would bet if a product was in need of repair that was beyond them, they would just replace it, and send the defective unit back to one of their sources for repair, and resale as used, or markdown merchandise.
Why would you assume LP does there own repair on everything, and even if they do, why would you believe that they could not find qualified personal to do said repair. Regardless of how people feel about LP, they are likely the largest scuba equipment dealer in the world. That did NOT happen without some SERIOUS inside connections.
One thing people never question is why if LP is so bad for LDS's then why do the LDS's supply them? The answer may seem obvious, but is that not a bit like the Rabbits in the Book "Watership Down".
