Welcome to our forum.
I have some concern re the 5 wire requirement with HS as I already have 220 4 wire (including ground) service to the existing pad (where the old spa was) in 1" pvc electrical conduit and not sure if I can pull two more wires through. Have # 8 wires now, about 45 feet from existing panel. Would add the GFI panel. (included with HS, not with S-Dance - though may get it thrown in)
I really loved the dimension one - tho did not wet test it - and thought it would be one to consider - the model I was interested in was the Lotus Bay. However, the initial quote re cost - which I was told was the dealer's discounted price off of mfgr recommended price - was, I believe, about $10,500 or so. Just looking at that model made me want it though. If the cost for that model would come in close to the Vanguard and Optima I would definitely consider it. A beautiful piece of work.
