Gotcha - appreciate the advice and agree its a lot of money so certainly worth thinking it over and overA lot depends on the user.. If 50% hate them, then 50% love them.. I find that they are not at all like a standalone spa from a comfort point of view. I like being able just jump in my spa on the spur of the moment, and not have to wait an hour for it to warm up. I like the additional jets etc.
That said, I am not saying don't buy one, I'm just saying why spend $20K on something you might not use.. If you have been in a gunite spa, and like them, it is all the more reason to buy one. If you have never been in one, it just make sense to know what you are getting before parting with your money.
