Being affiliated with a shop goes a long way though, allowing access to shop equipment, rentals, service, daily customers, dive club, travel, industry networking, etc.
Hi there Moonglow, I'll chime in with a different point of view on this. I'd say my perspective (as a student) is something like this...
I have a favorite local shop, but I can't really claim I'm a fiercely loyal customer to them. I've bought some gear there, but I also buy gear from different places depending on who has what I am looking for, what deals they're offering, etc. The local shop is the one I like to drop by and talk to the people there. I'm sure they'd be okay if I talked less and bought more, but I like the people so they're stuck with me. I've had a few instructors for open water courses at this shop and enjoyed them all.
Technical training though is, to me, a special consideration. It's something you are committing a lot of time, money, and heart to. It's not "stuff" you're buying, but a life experience you're investing yourself in so to speak. Shop affiliation is nice and in my case I'm glad to be able to work with my instructor through my preferred shop, but to me considerations about the shop don't play a role in the decision making. Finding the instructor that's right for you is the only truly important thing. Once you have found that, be sure to consciously recognize your find as a real gem. You may find other teachers you click with here and there in life, but it doesn't happen every day.
So to me, technical training is such a "special" undertaking that if you've found that instructor you click with, that's the only thing that really matters once you strip away everything else. I wouldn't really consider rotating through various shop instructors, all of whom are pretty good, if that's how my favorite shop did things (they don't, this is just an example). If for some reason my favorite instructor lost affiliation with my favorite local shop, I'd think it was a shame, but there wouldn't be any sort of decision I'd have to face because of the event. I'd just follow him to wherever he moved to, and I really wouldn't bat an eye if that did happen to be his garage.
And Moonglow, please understand that when I say "you" above, I don't presume to be schooling "you" yourself, it looks like you've done a looottt more diving than "me". Potential students out there considering this kind of training and reading this, I mean
you.
That's my dive philosophy for this month--
