Janda,
Good luck in finding the spa that works for you.
I didn't know anything about Saratoga, so I jumped on their website to learn a little bit about them.
Perhaps it was right in front of my face, but I didn't see any mention of their warranty. I even looked over one of their owners manuals and couldn't find warranty information.
I would want to know how their warranty stacked up against the Hot Springs tub?
Who manufactures their pumps and controls. How do they build their frames?
These are some of the questions I would want answers to.
Enjoy your hunt! I just finished buying cars for my wife and myself, and found the car buying process to be a breeze compared to my hot tub search.
