building your own in ground pool questions....

Hello, new here! We are getting an inground pool. Trying to research and get as much info as possible. I did read the "how i built my own pool" website that I saw someone on here recomend.

It looks like they purchased the pool its self from a pool builder in their area...

Im wondering if anyone here has bought a pool kit from National Pool wholesalers or one of those places that sells the kit itself?

We are located in MA so if you have a pool builder you would like to recomend that would be great too!
Thanks!
