I am looking for the address/name/telephone number, of a regulator mechanic in Key Largo. He has his own shop and that's mostly all he does. He was very helpful once, but my memory is fading. Is he still there? Any information would be appreciated. Thanks. Anyone like that in NYC? ( I'm not sure I want Leisure pro to service my regulator and an LDS once cross threaded the primary hose on my first regulator).
