Semita:Overall , I am very happy with my purchase. Thanks all for the feeedback. The only problem I have had is that the plastic cover for the FDX-10 Balanced Diaphragm First Stage broke. I did not drop it or anything. I took it back to the dealer and they replaced it immidiately.
Has anyone else had this problem?
It seperates for service, I've had some that I use teaching clinics that get taken apart dozens of times that start to be loose but this is the first I've heard of a new/not taken apart a few dozen times one that the cover is not snug. I'm sorry you had the problem but glad your LDS took care of it for you.
PM me your address, I'd like to send you an Oceanic ballhat to offset the gas you used on the extra trip to the LDS.
Enjoy the Delta 4, it is an amazing regulator, the first time I breathed off one I was impressed and jealous because at the time I worked for another company and we had nothing that could touch it! Needless to say I'm happy to be with Oceanic now!

Best,
Chris
