As you say the Diamante is a brand name and the dealer must have had problems with selling that brand.If Diamante is a good maker of spas why would he have not dropped the other brands that i have never heard of Charisma and bringing in another brand that I never heard of Dream Maker.Unless you have heard of Charisma and Dream Maker and think those spas are top brands too? :DJohnny Thunders
