Advisability of retrofitting to a two speed pump

Thanks for the reply fellows. The 2-speed pumps sound good and I guess I'll try to wheedle 3 of them out of my pool builder. :)

As part of our original pool contract, he "included" $3600.00 worth of Hayward Goldline (Aqualogic) pool controls. Then later, he informed me that the control unit we are getting only has 4 outputs. I checked Ebay for the going price of a 4 output unit and found it for around $500.00.

Either there's some horrifically expensive options for Aqualogic, or the PB owes me $$$ in electronics. :)

Thanks again.
