As I have found out--there are 2 (or more) sides to every story. I, too, used to buy alot of stuff from LP. I have never had a bad experience with them, but I never bought anything that required a warranty, such as regulators and bcds, but overall was happy.
Then... I started working for the Local Dive Shop and got the 'other' side of the story. My boss (owner) does not like LP just like 99% of all the LDS's out there. Not sure of the exact reason, but mostly because they sell stuff so cheap and that is hard to compete with. All he asks is that local divers give him a chance first to match LP's prices.
Most people don't realize how hard it is for small dive shops to stay afloat. Also, if you spend time at your LDS, you get a more personal experience, keep up on current events, get better warranty service and get professional opinions about gear. Not to mention you can meet more local divers and maybe participate in events they sponsor or join the local dive club.
I know scuba diving is an expensive sport and we all want to get the best deal. Please give your local shop at least a chance to meet online prices and if you are not satisfied, then you can go to LP, Scuba Toys, etc. Most people want their money to stay in the local community anyway.
Happy Diving!
