Back up a minute. The only difference in a DIN regulator and a Yoke regulator is the different means of attaching to the tank. Other than that the regs are identical. For example an Apeks regulator that has been converted from yoke to DIN is the exact same as an Apeks regulator that came from the factory DIN. One fitting screws out and another screws in it's place. There are no extra parts in one that has been converted. So you could buy a Yoke regulator and a conversion kit for it, convert it, and you'd have exactly the same reg that you would if you bought it DIN. Course that's more expensive, because you have to get the conversion kit, but it also makes it more versitile in that you can always switch back in a flash if you need to.
Really? I did not realize that a Yoke 1st stage converted to DIN, and a factory DIN 1st stage are identical. I guess then, I wouldn't mind getting the 1st stage in Yoke and then converting it to DIN. (I would have gotten a DIN-to-Yoke adapter even if I got the DIN 1st stage. I would need the adapter for boats dives that provide tanks ... AL80s)
But, I think the LDS I visited really sucks if what you all have been telling me about the availability of DIN valves in the US is true... especially since I have rented and purchased quite a bit of gear from them (Sport Chalet) this year.
Thanks for the info.
