Read the manual? What's a manual?
Well Bruce,
The manual is the first thing I look at while investigating a product. I know the manufacturer of the Honda pump, which is a world class pump manufacturer, that supplies to the commercial/industrial/municipal markets.
Honda-USA picked up a couple of their pumps to market to the general consumer, but these are still high quality pumps.
Then,
I compare. Still reading manuals and tech info and bit of number crunching.
The same in a comparable Grundfos pump will get the job done several hours quicker, reducing electric costs, but the pump is about 50% higher in cost. That is well below the budget you mentioned, and the Grundfos has double the warranty.
A dock mounted, high quality, self priming centrifugal with all the crap on a line starter would blow your budget.
OK, you can all poke fun now!
