OK, I think I get it now. I think I'm leaning toward the SQS1072R, as I'm seeing some places say the UQS1102R has been discontinued (looks like HSQ125 is the replacement?) If I went with the SQS1072R, would I need a new impeller and/or diffuser? What about with the UQS1102R or HSQ125?

Any recommendations on two speed timers, or could something be built from standard electrical parts? I'm a former electrician, so I can wrap my head around the electrical side of things.
