Don't think I can help you too much on your manufacturer. I'm doing a DIY right now and researched quite a few and ended up purchasing from PoolWarehouse.com Their steel wall pools are manufactured by HydraPools using Samson Steel. I know a lot of the pools in our area are built with the same walls. Seems as though when you look at a lot of the steel wall kits being built, the panels all relatively look the same. I guess the true measure would be the warranty on the walls, the thickness, and coating.
