Just an update...one week and and we LOVE our spa. Really happy I decided on the Siberian. Loving the different height seats especially when entertaining friends. AS far as why the dc'd the SIberian, our Hot Springs saleswoman mentioned the fact that they did add the new spa. She also suggested that they decided to stop making the SIb because it was takign too many sales away from the Vista. I'm not saying it is better than the Vista , just that many people who wanted a bigger tub liked the fact the Sib was as almost as big and still about 1500 cheaper. She said, "basically we were competing with ourselves for potential buyers of our biggest Hot Springs models (Grandee and Vista) . Anyway, thanks for all the info at this site. Made me a more confident and knowledgeable buyer.
