Have I bought from Leisure Pro? Yes...wetsuit, mask, things that I call "disposables" for lack of a better term. Items which I accept they are going to probably over a period of time, wear out and I am not going to have a heartache over it.
When it comes to life support gear...which in my feeble mind is regulators, computers, BC or BPW, tanks, valves, etc., I don't screw around with looking at price as a first consideration. My first consideration there is whether or not they are an authorized dealer (and that means they are listed as such on the equipments home website) customer service and reliability are next. Is that a few more bucks? Most of the time sure. But over multiple years of use, it returns the investment. I have a couple of Poseidon regulators I use in my tech rig. It scares me to think how much I would be paying to have those serviced had they not been bought from a dealer (Scubatoys in this instance which is by the way a brick and mortar store) where I can send them in and get them serviced for 50 dollars each with free parts included.
I understand the whole "support your local LDS" after having taught for many years, but it is a competitive market and while I am not looking for them to beat internet pricing everytime on any given item, they ought to be able to get reasonably close, at least on high dollar purchases. Example...I bought a wing from one of the local LDS's in Atlanta. I could have gotten it from the internet for 50 dollars cheaper, but I wasn't too sure about the internet dealer being authorized. The LDS got the money. A number of years ago I bought a Delta VR3 computer and the same LDS wanted close to 350 dollars more over an authorized internet dealer, and the internet dealer was including a travel kit with spare o-rings, battery, switch hardware, etc. The LDS didn't want to budge. They didn't get the dollars. It's give and take.
The ability to buy over the internet is a wonderful thing, but common sense needs to prevail sometimes over the number of dollars coming out of your pocket. Will I give a local LDS a shot? Absolutely...but if there is a significant difference in price on a high expense item, I have no qualms about putting forth "You are charging me X number of dollars, and I can get it here for -X dollars, can you get close or match?"
