Wow, the more I read, the more I'm grateful for my dive shop (Dolphin). It wasn't the shop where I was certified, but it's the shop where I'll be doing all other certs because I like the store so much (though loved my previous instructor, who made the owner do the hawking.
I have quite a number of Mares products, including my regulator, which I love. I've brought my regulator into Dolphin a few times for various things, and they aren't a Mares dealer. The first time I brought it in, they didn't know me, but the girl there exclaimed "It's so little!" and examined it. The only negative thing they've said about it was that some of Mares' regulators can be a little more expensive to maintain. A few asked me how it breathes and showed interest. When I needed to rent an SPG while I was waiting for mine, they attached it with no problem, and without charging me extra or nagging me about where I bought it.
They've regularly given me great service, great advice, and great prices, and as a result, when I want a class, a trip, or a product they carry, they're my number one choice, because I've never felt any pressure by them for anything, and as a result, they've gotten at least a couple grand out of me or on my behalf.
Despite 'allowing' their customers to buy elsewhere and even off the *gasp* internet without harassment, regularly when I go in there, they are absolutely swamped with customers.
I didn't think this kind of service and friendliness was *that* unusual, but the more I read, wow!
