I have owned a 50D for I think about 4 years now and I have only had one experience of a failure. I was diving in Roatan about a year ago at a depth of 80 fsw when it became harder to breathe. I pushed the purge button and nothing happened. The next breath was the last - nothing worked. I switched to my secondary and aborted the dive. When we returned to the dive shop and opened the reg up, it turned out that a spring had somehow slipped out and would not allow the valve to open. It was a bit exciting, but I do not think that I would necessarily blame the reg. I have been very happy with it othewrwise. I have not used it in cold water yet, so I can not address that issue for you. Good luck with your search.
