In reference to the posted link, why does it say "This is the real deal" when comparing the side inlet vs the center inlet? Does it make a difference other than aesthetics? I would think I could just install an elbow into the center inlet model and till get same effect.
And also, is $130 pretty much the going rate for the March pump?
I don't think the inlet orientation (center vs. side) makes any difference in the pump's performance - it would just affect how you configure it for your system. The $130 price was the best I found at the time for the 809-HS with a plug and cord.
