I was at my local dive shop last just chatting and I made mention that I bought myself a new reg (Cressi Ellipse Titanium) and that I got a fairly good deal on it from LeisurePro, $100 off since it was marked as used but in like new condition. After I said that he had a funny look on his face so I asked if he had heard bad things about it? He said that one of his friends had bought a reg (Atomic something or nother) from one of the online stores (Scubatoys i think... not trying to name bash or anything, just relaying the story) and had gotten a good deal on it but when he went to use it, it was breathing hard. So with this he took it to his dealer to have it repaired and the guy said the internals were gutted and replace with some junk components. Because of this, the guy from my dive shop didn't trust the online stores for important things like regs and such.
My long winded question is this... has this happened to anyone else? Is this fairly common? I'm a little nervous now about my purchase and wondering if its misplaced.
