I'm soooo confused. Three different pool stores in my area are all telling me different things. One says to go with the aluminum walls. It will take 40 yrs to oxidize. One says to go with galvanized steel/stainless steel service panel/rim. Another dealer who sells Esther Williams says to buy the cheapest aluminum I can find in the size I want because either way, it'll rust in a few years . I've just about given up on this idea. Can everyone pleaaassse advise me on your opinions???

My hubby would certainly prefer to go the cheaper route

Thanks for your help!
