I don't know if this link will work for you: http://tinyurl.com/39gyrh7. It's a Google Squared search for 'above ground swimming pool pump'. Click on the down arrow in the PRICE column and sort from A-Z which will then show prices from lowest to highest. There are a number of pumps at HP from 3/4 to 1.5 at under $200.

I'd put as little money as possible into the pool to make it functional for this year. How long is your swim season where you're at? Of course, the pump is something you can take with when you relocate the pool and it might make sense to get the best you can afford.
