Thank you.I also had difficulty sourcing. I used a couple of apps to do so, here's the final playlist:
Equipment Supplier Cost Pool light Florida Sunseeker $508 Spa light Florida Sunseeker $497 Pentair CCP520 filter FB Marketplace (used) $400 Flowvis FV-2 Amazon $112 Pentair Intelliflo Amazon $1802 Pentair Intellicenter FB Marketplace (NOS) $1081 IntelliChlor IC40 FB Marketplace (used) $250 Pentair IntelliValve AZPoolSupplies.com $215/ea Pentair 200k MasterTemp AZPoolSupplies.com $2171 Air Supply Silencer (spa blower) FB Marketplace (NOS) $126
I didn't list the white goods, because they were generally easier to find. There were also way more options in white good suppliers (although, I used 95% CMP).
