Ionheaven, if you can get the Envoy for approx 1200 dollars more, I would highly recommend it. If you spread that cost out over the 12 -15 years you are going to have the spa it is pretty insignificant but I can gaurantee you there is a significant difference between the Envoy and the Sovereign when it comes to size and pumps. It is just my opinion but you should definitely go for the larger Envoy. You will not regret it!!! I have owned my Landmark by Hs for almost 2 years and we absolutely love. I almost got the Sovereign due to the lower price but I am soooo happy we decided to get the larger Landmark. It is great for entertaining but it is even better having the larger tub when it is just you and a significant other.
