G'day.. I have a 5 year old Sundance Cameo. The ozonator is tripping the GFI, so I assume that, and it's age, is meaning that it is toast. It is a Spa Necessities 40765. Is there an online parts store that I can purchase a replacement? I have googled it, but can't come up with the exact match. Can it be replaced with a different model of ozonator? The dealer is telling me there is a next generation ultra violet lite system for $900.00 that is even better than ozone, but is sounds pretty pricey to me. Any suggestions?
