Hi Keith.
There is another company you should investigate- GULF COAST SPAS.
Until recently HydroSpa and Gulf Coast even shared the same manufacturing plant.
Gulf Coast Dealerships are wholesale companies and the owners are happy to help compare. They may also negotiate price.

Compare Gulf Coasts Englewood seating 7 and holding 400 gallons which I bought for $4200 (retail near 9000). It was so much more for the money. 45 jets, 10 hp (double 5hp motors!), Microban, the ozonator to keep it clean, deeper for winter soaks, less expensive maintanence ($16/mo. average) and better warranty with lifetime on shell, plumbing, heater and five years on the rest. I could have bought the smaller one around 3700 but wanted the 10hp.
My sister looked too and bought the same model in Austin, TX for the same price.
