Where I bought (Auburn Bay)
You have 4 pretty large builders -- Baywest, Cardel, Jayman and Cedarglen
my neighbor cribs for both baywest and Jayman, and he knows all the other trades as well...
He wouldn't touch Cardel nor Jayman...
Builders really are a firm of archetects, project managers, supply chain managers, vendor managers and sales contractors... at the end of the day, the general contrat manager makes the deal that is in the best intrest of the firm... that sometimes either works as a benefit or disadvantage for the end customer.
From what I've heard from my neighbors and the trades that my friends know who work for various builders... Cardel treats the trades the worst and pay the worst. They also have very poor post purchase support.
Jayman is simular to a degree, but as they have a tendancy to push one or two particular models, their trades have it nailed, for lets say the "allure" model. Post delivery support is fantastic... BUT they do undercut and change their trades often to save a buck or two. No loyalty and sometimes results problems again to the customer. For instance, all the rolling mix drive ways (used by both Cardel & Jayman) this year have to be sandblasted as the mix was terrible.
