Its to bad to hear about the hard sell, But D1 is a great product, i am not a fan of the salt systems, i will take a great ozone system any time.... i can tell you that D1 has been around 1977 out os San Diego area, there customer service is one of the best we have encountered in this industry, i would definetily sit in both brands , but as i say on this sight if you are not buying from a specific dealer don't do it. buy were you are comfortable with....good luck with the spa hunting
