Replacement pool pump

I have an in ground vinyl liner pool approximately 20K gallons. I need to replace the pump motor but considering entire pump and motor as I replaced motor and gaskets a few years ago and they are leaking now.

My motor is a 1 HP USQ1102 that feeds to a Starite Cristal flo T-240BP-1 filter.

What is the most economical replacement pump/motor you sell?

The USQ1102 is the motor number; that number can be mounted to dozens of different pump housings. Those housings can have various flow rates. To give an accurate suggestion I need to know the model number of your pump housing. A few pictures of the pump housing would work as well.
