Purchasing my first tub, narrowed it down to the sundance Chelsee, the jacuzzi 385 and the wellis Elbrus 230 deluxe. I have wet tested the wellis and sundance, the wellis seems to be the best to me but I know nothing about hot tubs. Can't find any reviews on wellis but going on reputation for jacuzzi and sundance. The wellis is the cheapest at 8k followed by the 385 at £10,700 and Chelsee at £10,750 without radio. Sundance reps believe sundance is better than jacuzzi and Jacuzzi reps better than sundance. They both say they have patented parts such as sundance with their no moving parts and better filteration. Can someone clear this up, are one better than the other and anyone got any advise about wellis? Any advice is very much appreciated
