OK, thanks for the explanation on no mask breathing. In my first pool session, my instructor had me put my face (no mask) in the water, and breathe through my snorkel normally. I had to repeat until I was comfortable doing this. Another thing my instructor has his students do is put their faces (no mask) in the water before their first OW dive. This gives one a good idea of what to expect when it's time to do mask clearing in 46 F water, and I'm glad he had me do this! It was still a bit of a shock when I flooded my mask, and I knew what to expect.MechDiver once bubbled...
No mask breathing lasts longer and, for some tasks, involves swimming without a mask. At least, that was the standard when I took my OW.
PADI does not do mask swapping until DM training.

Stephen Ash: You raise very good points! Also, as I mentioned in my original post, my instructor covered things listed as an N for NAUI on the diverlink comparison chart. I should rephrase my comments to include "As part of their initial research". I certainly did not mean to imply that this diverlink page be the sole source of information, or a deciding factor. I chose my instructor based on someone else's previous experience with him, not on the certifying agency. Did I get lucky? Judging from things I've read on this board, I think I did. I certainly would have never asked all those questions Mike F. mentioned in his post, or have even thought about one agency being "better" than another.
