Need help deciding on a pool! plz!

Hello all, i live in South Florida. Im looking into a 21' Round above ground pool. I spoke to a local installer, which also sells the pools and he started that Resin pools are the best, then comes aluminum..

I stumbled across "thepoolfactory.com" which is nice as allowing to pick packages and such but can't seem to find "resin" pools..

Id like to stay around $2500 including pool and accessories IF possible, but don't want a crap pool... so if i need to increase i will. Please point me in the right direction. Do you recommend buying the pool from the installer? I got a quote of $2900 for a "full resin 54" package" + 725 install/delivery fee but didn't include any additional info as to brands ect.

I also just so EZ panel pool which is for In ground installs, which id love to do and would probably be okay spending the extra money to have this done, but i don't want ANY worries of issues with the wall collapsing which is what I've heard with normal ABG pools. Anyone have any experience with EZ panel in ground installs?

Thank you !
