Ok, Got off the phone with the dealer who showed us a Resort Spa model in his showroom. After explaining to him that I can find no info besides the brochure he handed me, he advised that resort spas are made exclusively for his dealerships by none other than Artesian spas. Has anyone heard of these or own one? I would be very interested as the model they have available #840B for wet testing is sexy as hell and priced at $6499.00. BTW, it uses full foam technology
