Unfortunately there is not a direct competitor. I personally feel that the Caldera Makena, while a larger hot tub and similar price, is not quite an exact comparison. The Flair has ozone standard, better filtration, more lighting and ACE compatibility. Likewise, the Caldera Tahitian will be a "Step Up" within the product lines. I feel it has a nicer cabinet and base and a nicer therapy experience, but will come in at approximately 25% more. If you move into the Tahitian, then the Hot Spring Aria is the comparable model.
