Yes, Sundance is a great spa. I don't think you can go wrong...if it works for YOU.
Spatech is right when he said one spa may work for you but not your wife and vice versa. I couldn't get my husband to wet test anything. He said whatever worked for me would be fine for him. It came decision time between a Jacuzzi 385 and Marquis Epic. I told him we weren't buying anything until he tested. I thought I was sold on the J385 and when he tested it, the lounger didn't fit him and I floated in most seats. I had tested HS, Sundance, Jacuzzi, and Marquis. When we tested the Marquis together--a fit for both of us.
I'm not trying to sell you on Marquis--the point is you won't know until you try them all.
Good luck!
