Welcome to our forum.
Thats interesting. Do they have info on the web ? I am curious.
Only trying to offer a suggestion here but Marquis has just come out with some new additions that seem to be like the Caldera you are looking but for the same price of just under 6k you can get 41 jets, 2 pumps, ozone with synthetic siding and up graded cover.......from the specs I see this would seem to maybe more tub......
our local Watson's sells both the C30 as well as their other brand C45. Jr
