Yesterday I replaced a functional but extremely noisy single speed 1 1/2 hp pump with a Hayward Max-Flo VS. variable speed pump (sp2302vsp).
I am happy! It is extremely quiet and works as advertised. If anyone has a question or comment I would be happy to provide my experience with installation and ownership.
i bought it from Amazon and it was the older model (last years) to save some cabbage.
