Sometimes I wish all of you with bad LDS's could visit a cave shop here in cave country.
Imagine walking into a dive shop, and them having EVERYTHING you need. Need a $3500 scooter? There's 3 in the corner. You can rent them too. Need a high end regulator? They've got 3-5 brands. Need a BC? Sure, here's a selection of BP/W by 3 or 4 manufacturers or a DR Transpac/Zeagle back inflate. Dive computer you say? How about a VR3, or a Vyper, or a NitecHE? Lights? Canlight in big, bigger, or video, and backups too.
Need to rent tanks? Sure, you want AL80s, Steel 95s/130s, or do you need a AL40s for oxygen or EAN50? Custom blend nitrox, sure no problem.
Get directions, local dive conditions, referrals to another shop that will have just what you need (they call ahead), etc.
The first time I walked into Cave Excursions and Extreme Exposure, I looked around at everything. And in both instances I had exactly the same reaction. There was no crap, all good stuff, and at prices that were the SAME as the online prices. And how about the dive now pay later program for regulars. Settle up your gas bill at the end of the dive day, or dive WEEEK. No hassles, no problems.
The shop owners are divers. Their employees are divers (usually avid cavers), they host product demo days, customer appreciation days (picnics, free stuff, auctions, swap meets), and there is often free coffee, snacks, etc.
A LOT of LDSs could learn some lessons... However, there are very few customers going in who don't know what they actually want. This tends to streamline product.
