Hi, Spookyfoot!
After wet-testing all spas known to man (on the West Coast, that is) two times over, we decided on the Artesian Piper Glen. We have the concrete poured, the electrician's been out, and we are just awaiting the arrival of our dream spa! Very pleased with the design/layout of the spa, and the individual pumps/controls was the clincher (bye-bye hard to reach diverter valves).
Another thing I would like to mention is that this has to be the most quiet spa I have ever been in (in my entire life).
I know someone posted on this forum that they were going to conduct some decibel testing in the near future, and perhaps this person could bring the Artesian Piper Glen into the mix.
Just my two cents, for what it's worth. Good luck!
