After talking to Richard from divetank.net today, I have to say, he is great to speak with on the phone. Very informative and helpful. Just as whois reported, divetank.net is located in BC, Canada (I had to ask after I heard his Canadian accent) and based on Richard's information they are an authorized Suunto dealer, meaning full manufacturers warranty with warranty card and ability to register with Suunto (I asked him about this). LDS prices aren't even close to what divetank.net offers, even with a history with my LDS (training, gear purchases, internation trip coming up, etc.).
The way I look at it, an LDS can't do a thing with a dive computer anyway. They are simply a waypoint to ship it back to the manufacturer for work. To me (and many others), taking care of shipping a unit simply isn't worth the 75-100% markup an LDS demands. Now regs on the other hand. . . at least the LDS can maintain/repair them in house, which is at least worth SOMETHING.
The biggest reason LDS's can't compete on price is because they choose not to. They don't offer the deals that lead to moving significant amounts of inventory (because they "have their hands tied"). Since they don't sell a lot, they don't order in quantity, meaning they pay more per unit, plus have to amortize more shipping cost per unit as a result. It's a discouraging trend, but it doesn't mean I (or anybody else) should work more hours to afford the exact same gear. This is a simple truth of a free market society.
