I'll move this out, and let others reply.

My personal experience with Jandy products is limited, and I have no direct experience with in-floor cleaning systems. But, for what it's worth, I have a very low opinion of Zodiac's corporate integrity . . . and they own Jandy. For that reason, and others, Jandy would be at the bottom of my list of pool equipment manufacturers.

More generally, a 2HP variable speed pump is NOT an efficient choice, unless you NEED a 2 HP pump. Variable speed pumps can be turned down to act like a 3/4 HP pump . . . but they'll rarely, if ever, be as efficient a 3/4 HP pump as one that's designed to be that. So, the answer to the other part of that question, about variable speed pumps being worth the month, the correct answer is a firm and definite, "it depends on your pool's design, volume, use, and piping".

Regarding in-floor systems, including Paramount's, I've repeatedly heard other guys talking about them. My very strong impression is that (1) if they are badly installed, they NEVER work well, but (2) that if they are well installed, they'll work for 5 years or so, and then become unrepairable. So, if you plan to live at this house for more than 5 years, I'd find someone who has a system they still like after 10 years!.
