I was a Sunrise dealer from 2011-2014 before we switch over to Marquis. Not really sure where to place Sunrise. I personally cannot justify spending a premium dollar on a brand/company that is not premium. Generally speaking, we did not have many issues with Sunrise. We only carried what is now the Signature series and the Sunlite series. Company support was ok, nothing bad, but nothing good. They basically have one person, or point of contact for service and if she is not available, there is no one to help with tech support.
What I liked about them when we carried them was that they used the Balboa BP controls, Sunstar covers, and Balboa(Sta-Rite) and Waterway pumps, basically pretty good to good quality components that should always be readily available.
My concerns about the Paragon series would be the "Insulated Eternalwood Cabinets". The ones we had with those warped pretty badly and I'm in Wisconsin, FWIW. The original version of the touch screen controls were not the most reliable, but I haven't seen what Balboa has done with them over the last 3 years.
If I were you I would pass on the wifi and the UV. I noticed no difference with UV and the bulb has to be replaced every 18-24 months. There is enough negative info on the reliability of the wifi module.
The Paragon series was priced at a premium so I'm guessing that the price you were quoted is fair, but keep in mind I haven't seen pricing since 2013. Again, as Sam said, I think there are many other premium manufacturers I would look at first before Sunrise. However, you have to factor in the dealer and how comfortable you are in the spa. Do you have other local options in terms of brands and dealers?
