Welcome to our forum.
I'm looking at 7400 for the Artesian and 10,600 for the Caldera. We have dry tested both and prefer the Artesian's arrangement for our needs and obviously the price (it's an inventory closeout). We're also getting full foam and the "footblaster". I liked the Caldera too, as well as their warranty and what I've found online about them, but 3k difference is tough to ignore. The dealers seem roughly comparable with generally positive comments. I do want to get a wet test scheduled, but really wanted to see if we were chasing an albatross with the Artesian. That big a difference just seemed too good to be true!
