There are many things to consider when buying scuba gear. Most shops are pricey because they have a high overhead. A given piece of gear can be 3 times as high as an online shop, but an authorized dealer stands behind their gear with warrenties. Parts are included in some warrenties as well as labor. On the other hand, if I find a given regulator dirt cheap from an online store like LeisurePro, it still may be cheaper to buy another one if it breaks than to pay dive shop prices. Some online shops are authorized dealers as well. You need to go to the brand's site and they will tell you. Aqualung does not authorize online sales. Oceanic does, but only if you see their "shop and buy" logo. Ebay has Ebay stores as well as private sellers. If you use PayPal then at least you have recourse up to $1,000 if you get rooked. Oh, and strangely enough my dive shop has better deals than they advertise online! Maybe it's because most manufacturers have set prices online for all distributers and shops. Bottom line is some dive shops have to sell high to stay in business, while others sell high to increase profits. I don't blame them. It's just the business. I will leave you with this: Not every dive shop is looking out for you, nor is every dive shop trying to rip you off. If you go to your local dive sites, the divers and the site operators will tell who's what. And don't just take one person's opinion. Don't even take mine! Do your homework. Don't allow anyone to pressure you to buy anything. If you go to scuba.com, you will see some gear with a "scubalab's choice" logo. They are an independent testing group who has tried the stuff out. THEN FIND A DEALER TO SEE IF IT FITS! The rest is now the price...
