DIY inground pool kits

Thinking about purchasing an inground pool kit. I've been doing some research and have contacted a couple of companies and gotten prices. I'm not overly concerned with the process. I'm lucky in that I have an uncle who can excavate the site and also does concrete for a living. A local pool company also subs their concrete work to him.

My question or concern is what company to go with. I have quotes from poolproducts (through in the swim) as well as pool warehouse. I've read and looked over royal swimming pools and some people have used them.

Any recommendations?
