Its a misnomer that EE doesn't have sm tanks. They have for years. Believe it or not there's some of us that have gue training that still enjoy sidemount and sidemounted bailout for our non-GUE approved CCRs. EE is also just a dive shop. Although there is clearly a strong, direct link to GUE, EE is more than happy to serve any diver regardless of training. I brought all my sm tanks and regs to EE for fills and service for years prior to getting GUE training.
At the end of the day, EE is just another dive shop trying to make money. The difference is the level of professionalism that you don't get at alot of shops. And I'm not saying that EE is the only shop to use. It also has its pros and cons just like other shops.
You will definitely see more sm divers at CCDS, which is also a great shop.
