After consideration of all comments posted, I decided to go with the dealer I felt most comfortable with - National pools and spas in Robbinsville, NJ. Had to travel from Pa.
I purchased a Sundance spa, Hartford model with light kit. The dealer threw in the SunZone Ozone system, the optional CL circulation pump, 880 warranty, rocker cover, steps, chemicals for the first month, delivery and set-up. I wound up paying $7795, and I think that's a very reasonable price.
Again, thanks to everyone for your knowledgeable insight, and once I'm up and running I'll update.
