I need some advice on the Sundance 780 series Camden hot tub. I guess on my last post, just did not warrant any replies. I have narrowed it down to this tub to purchase, I am looking at a 2012 leftover on the demo floor, Could anyone tell me if this is a reliable model for Sundance. I Need to know, is the Eco - Wrap they sell for this tub worth purchasing on a new model ? They say it reduces costs by 25% , also is a stainless steel heater something to worry about (reliability) ? I really want to know about the Eco - Wrap, because that will determine if I purchase new or the leftover ( the leftover does not have it installed) please all replies are appreciated. Thanks !
