I'm sure there are many good dive ops in Coz. Board members talk about them all the time. I started using Aldora and liked them. Yes, I always come up in the yellow and usually with about 1000 psi in my tank or more but I like the operation and DM's so the extra money is a non issue for me. If I somehow found another op I liked as well that was cheeper I would use them if Aldora goes OOB, changes service, or the like but until then us Aldora fans will keep them open.
