My 2004 pool was built by A&S in NNJ (Green Brook office, but done out of Pennsylvania.) PoolGuyNJ pretty much has it right. Shell/coping seems very well-done and is still perfect after seven years. Plumbing equipment was all Pentair or Waterway and is still going strong. That's the good news.
Bad news is project management was non-existent and delays were constant. I had permit in February and they barely got it done by mid-June. No one ever had an idea when anything was going to be done. Plumbing was poorly done, placed on the side of a hill and threads were glued in. The whole thing fell over in the first good rain storm. They did a half-assed job putting it back together. I redid it all myself the second year, turned the filter around, installed unions, and got it right. No problems since.
The biggest disaster was post-fill quality assurance. There was somebody assigned as liaison right up to the fill, whereupon he disappeared. One guy in Pennsylvania, with one extension that was never answered, was responsible for all post-build follow-up. No one else would talk to you--they just referred you to the unanswered extension. You could leave messages, but he never called you back. Problem resolution (and there were a few) was a nightmare.
Summary: I ended up with a good pool at a good price, but it was a nightmare getting there. Maybe they have improved since 2004, but I doubt it. I do not recommend. I am very glad I used them only for the pool itself, I would have gone crazy if they had reponsibility for anything beyond the coping.
Other comments: They put all the returns in the shallow end. They did all 2" plumbing, including the filter internals on the Waterway DE filter. They just threw the equipment manuals on the trash heap--I had to rescue them as stuff arrived.
