First off, I want to start by saying I don't want this to turn into a rivalry thread, if it does, I won't have any issues with a moderator closing/deleting it.
I've seen a lot of people talking bad about one agency or another on the boards, both about the training they offer and about the way they're organized in general. I'm looking to get my AOW soon, and after that I'm hoping to take Nitrox and a few other specialties. I don't have any kind of loyalty to one outfit or another, but I earned my OW through PADI, now that I'm looking into more advanced education, I'd like to hear what you guys think is the best agency out there.
My local shops are both only PADI, and there's only one NAUI place in Montana, I'm not aware of (but haven't exactly looked) any other outfits existing here. Let me know about your good and bad experiences with one agency over another, but like I said, please don't start a war on who's better or worse.
