I ran across this site and though perhaps some of you would enjoy it. I sure did. Hope it isn't old info for you.
It's a website created by a guy who GC'd his own pool and he tells about his experience and thought process for the decisions he made in desigining and equiping his pool. He had gotten bids for a pool and had even talked to the BYOP people but still thought he could save more by doing it himself - and he did.
Some of the site you can see without registering, some of it you must register. There are actually others who have also shared their pool build experience, as well.
