Thanks Mark, yeah if cost wan't a factor, I'd like the Pentair Intelliflo, replumb and be done with it, but I'm trying not to spend 900-1000 on a new pump, that's why the US motors unit is appealing as a retrofit, especially since all the timer controls are integrated on the pump and you wouldn't need to get a switch or new timer. FPL is also not offering any rebates for vs pumps when I last checked. The replumbing for better efficiency would also help. The vs is not out of the question though. My one worry with them is from what I've read, if the electonics go, there no replacement modules available even though they are listed on parts lists and you have to replace the whole pump. With the electric storms we have here, it makes me nervous. Solar is out since we live in an Oak Hammock and have not enough sun to support one, along with a northern roof exposure where it would need to go.
