Thanks for everyone's help. I have been researching for weeks. The two main dealers in the area do provide stainless steel service panels, steel bottom rail and the walls I believe are the galvanized (steel) not true steel as it's a copper alloy (???). Is that what you mean by steel walls??? The other dealer is actually in Hornlake, Ms (Splash Pools). He is the one that told me to buy an aluminum one. He referred me to someone who sells Esther Williams aluminum pools. Is the aluminum one stronger??? I do understand about the warranty; I guess maybe I'm asking if you prefer the aluminum( supposed to be stronger) or the galvanized walls? Wouldn't the steel bottom rim rust and the aluminum would oxidize?

Thanks,
Teena
