I agree with tom winters, fairbanksdiver, and awap. I'd rather service my own regs and have myself to blame if something goes wrong then trust somoene I don't know. I mean for some of the prices these LDS's are charging you could buy a new reg online. Also if your diving in a manor where a regulator failure of any kind is life threatening I would maybe rethink your diving practices. If you can't easily do an ESA ya know it might be good a good idea to have a backup air supply (cough cough pony/doubles) in addition to your buddy. So much for it being some magical LIFE SUPPORT EQUIPEMENT. Now whose the moron.
