Well, we finally settled on the Niagara by Caldera. $9500.00 including tax, steps, cover lifter, 220 sub panel, delivery,set up, filling, balance the water, move my propane boiler vent so I can build the deck, silver cartridge, and starter chems. The dealer is three minutes from my house and has a good reputation around town. Best of all we love the tub and don't float in it. Thanks to you all for the expertise and advice. I learned a lot and it made my purchase more enjoyable. I feel like I got a better deal because of what I learned here. I'm hoping for an enjoyable experience with our new tub and will likely check back for advice on caring for the water. Thanks again everyone!!
