450-460 watts of power and move
closer to 275 to 300 gph of water.

If what you say is true, it would be insanity to not pay full price
for a Sequence pump. Compare and contrast the GPH-PER-WATT, and then
do your power bill every month for year.

E.g., Sequence Cimarron, 3600 GPH, 160 WATTS.

Unless you're living in a hydro electric area, the decision is
obvious.
